Test, Culture & Specialty Tubes

Glassware is one of the staple products used in every laboratory and in this new

glassware catalogue, Thermo Fisher Scientific offers you a range and choice of

products which will suit every budget.

The catalogue showcases a host of leading glassware brands, offering you both

choice and convenience when selecting glassware for your laboratory. Quality

and precision are the hallmarks of the glassware range available from Thermo

Fisher, so irrespective of the brand you select you can be confident you will

receive quality products.

Readily available stock is an important factor when ordering glassware items. To

assist you in this process, the catalogue denotes those items which are generally

available from stock.

The availability of appropriate certification is increasingly becoming an important

factor, particularly when buying volumetric glassware. Recognising this need, the

catalogue features products which again provide you with several options relating

to glassware calibration and certification.

While the catalogue is intended to showcase the main glassware products which

are readily available, it is not all encompassing. If you are unable to locate an item

you require, please contact your local Account Manager or Customer Service

Representative and we will endeavour to source the product on your behalf.

Finally, we trust you will find the catalogue beneficial and would encourage you

to take advantage of the extensive knowledge and expertise Thermo Fisher have

available to assist you in sourcing all your glassware needs.

Kimble Brand KIMAX beakers provide strength and durability from top to bottom. Uniform sidewall and bottom thickness, especially in the critical radius point of the heel area, provides excellent mechanical and thermal shock resistance. The chemical and physical properties of KG-33 glass ensure high resistance to heat shock and chemical attack.

Heavy Duty BeakersKIMAX beakers with thick uniform walls throughout and extra wall thickness built into the evenly tooled top rim. Spout is designed for optimum performance. Heavy construction is intended to prolong life with harder than normal usage (i.e. mechanical shock). Not recommended for use on hot plates where significant thermal gradients exist due to lack of agitation of contents or absence of a temperature control. All sizes have a durable matte finish marking area and a white graduated scale. Designed from ASTM Specification E960, Type II requirements.

Disposable Culture TubesThe LabServ borosilicate rimless disposable culture tubes have a low thermal expansion coefficient and high chemical resistance, making them ideal for use in the medical, pharmaceutical and analytical industries. The LabServ borosilicate rimless disposable culture tubes conform to USP, Type I and ASTM Type I, Class B standards and are available in a wide range of sizes from 6x50mm to 25x150mm.

Borosilicate glass KIMAX-51 composition assures the best all-around chemical durability of commercial glasses now available for laboratory ware. Complies with ASTM Specification E438, Type I, Class B glass requirements. KIMAX-51 has excellent chemical resistance against sodium leaching - a factor common in soda lime glass products. These are premium quality tubes with sturdy, uniform bottoms and consistent lengths. The 10 and 12 x 75 mm sizes are suitable for cell washing procedures. Tubes are packed in convenient trays for ease of use on bench tops and in drawers. The 10 and 12 x 75 mm sizes fit into Kimble 73510 stainless steel dispensers. The 6 x 50 mm size is often referred to as a “Durham tube”. Trays are shrink wrapped in plastic film with tubes remaining in constant alignment for protection against in-transit breakage and contamination. Designed from ASTM Specification E890.

Glassco NABL Accreditation

Care and Use — Cleaning Methods

Glassco’s Calibration Laboratory has undertaken accreditation for its system for calibration and testing as per ISO 17025:2005. Glassco’s Calibration Laboratory is NABL approved. NABL has an MRA under the Asia Pacific Laboratory Accreditation Cooperation (APLAC) and the International Laboratory Accreditation Cooperation (ILAC), which means the calibration provided to customers for volumetric ware is acceptable in calibration laboratories worldwide.

Care should be exercised when using most cleaning solutions as they can cause skin irritations or severe burns on contact. Dilute solutions become concentrated as the water evaporates; therefore, always flush the exposed area immediately with large quantities of water.

The list of methods given here is by no means complete, but offers a fairly wide variety and should cover all the usual contaminants, as well as the more important special cases.

It is frequently desirable to give glassware a preliminary rinse or soak with an organic solvent to remove grease, followed by a water rinse. The rinsing with water must be done thoroughly if acid will be used later to clean the glassware.

Unless autoclaving is necessary, glassware should be cleaned as soon as possible after use to avoid setting and caking of residues. Pipettes, for example, may be placed in a convenient jar containing a weak antiseptic solution immediately after use. Autoclaving is necessary to disinfect glassware that may have been used to contain potentially dangerous biological fluids.

There is a wide variety of cleaning agents available that will remove surface contaminants such as silicone and other organic and biological residues that may interfere with trace analyses. These cleaners are available in biodegradable, phosphate-free and chromium-free formulations if desired, and can be obtained from Thermo Fisher Scientific.

Results of calibration are guaranteed for precision as per the DIN, ISO, USP & ASTM standards. The calibrations performed by Glassco calibration laboratory are conducted under ISO 17025:2005.

NOTE: If wiping or other mechanical cleaning action is necessary, it should be done gently using non-abrasive cleaners and wiping materials. The use of abrasive materials will damage the glass surface, degrading its inherent strength.

There are some specific contaminants that may require specialised cleaning methods, and some are given here: 1. Permanganate stains. Use a mixture of equal volume of 3% sulfuric acid and 3% hydrogen peroxide.2. Iron stains. Use a solution containing one part hydrochloric acid and one part water.3. Bacteriological material. Glassware should be soaked in a suitable disinfectant solution or steam autoclaved followed by cleaning with a suitable agent.

CAUTIONS: Before using any cleaning solution, refer to its Material Safety Data Sheet for precautions to be observed during use. Some of the cleaning materials used may leave trace residue unless the rinsing process is carried out thoroughly. While such traces may not be harmful if the object of cleaning is to prepare the glassware for calibration, they can give trouble in certain laboratory operations. When glassware is to be calibrated, the final rinsings must be performed with distilled water. If an article is to be dried after cleaning, as is necessary for all vessels marked “To Contain”, ethyl alcohol or acetone (American Chemical Society Specification) may be used. Drying may be hastened by blowing clean, dry air into the vessel (or sucking the air through the vessel). Efficient air filters must be provided to remove any particles.

Glassware Safety

Care and Use — Cleanliness of Apparatus

You play by common, ordinary, everyday rules, the kinds of things you’d do naturally if you just took time to think about them:1. Don’t get cut – it hurts you and your productivity.2. Don’t drop glassware – avoid the bruises that lead to breakage.3. Don’t use chipped or broken glassware – it’s dangerous and breaks more readily.4. Don’t mouth pipette – you could inhale a toxic substance, burn your mouth, or cut your lip.5. Don’t leave pipettes sticking out of beakers or flasks – an invitation for an accident.6. Insert tubing carefully. Use a protective towel for your hand and lubricate the tubing.

The usual criterion of cleanliness of glass apparatus is uniform wetting of the surface by distilled water. Certain contaminants, especially grease, adhering to the walls prevent them from being uniformly wetted, and there is a tendency for water to collect into drops.

Imperfect wetting causes irregularities in capacity of volumetric glassware by distorting the meniscus, and also by affecting the volume of the residue adhering to the walls after emptying instruments calibrated to deliver the indicated volume.

Even when the surface of the vessel is uniformly wetted, variations in the apparent capacity still may occur, due to contamination of the liquid surface by minute quantities of fatty or other organic substances which produce a change in surface tension affecting the shape of the meniscus. The cleaning, rinsing and drying, therefore, must be carried out in such a way as to prevent this from happening.

The choice of the procedure to be used in cleaning glassware depends on the nature of the contaminant. In many cases special reagents or methods must be used to remove a particular substance. Before listing the more important methods, it is desirable to make a few general statements.

GlassGlasses used in chemical apparatus have excellent resistance to acids, except hydrofluoric. Strong alkaline solutions, such as hot caustic solutions, will attack any glass if contact is prolonged. This is true even

7. Dispose of broken glassware in a special receptacle.8. Carry large containers carefully, using a bottle carrier.9. Clean and rinse glassware very well with deionised water, then let it drain dry on a clean, lint-free towel.

To back up the rules, you need a formal laboratory safety program. It begins with a written safety policy, a safety committee, and regular safety inspections. That way, you can investigate accidents thoroughly, keep a record and analysis of them, and promote safety awareness all the time. It could lead you to the best safety record ever.

though a particular glass may not exhibit any visible effect, due to the solubility of the reaction products. Dilute detergent solutions, up to about 2% strength, will have no serious effect on the glass, unless the glass is exposed for unnecessarily long periods or the detergent is allowed to dry on the glass.

Coloured GraduationsThe scales and inscriptions of many items of Kimble glassware are coloured by staining a thin layer of the glass. Since the coloured portion is of the same composition as the glass object, the resistance to chemical attack is the same as that of the rest of the glass. Here, the colour can be removed only by dissolving a layer of glass from the surface. Some Kimble volumetric glassware has fused on, ceramic enamel printed lines and inscriptions. These fused-on enamels are quite resistant to acids and alkalies. In most cases they should last as long as the piece of apparatus if cared for properly. However, by their nature, they cannot be as resistant as the ware to which they adhere. Consequently, the graduated lines should not be subjected to prolonged immersion in acids or alkalies. Whenever the lines are wetted by reagents, they should be rinsed as soon as conveniently possible.

Safety PrecautionsWith many pieces of glassware, it is necessary or desirable to fill by suction when cleaning. Do not suck up acid or other cleaners by mouth. In fact, do not pipette by mouth at all. Use hand held, manual or electronic pipetting aids

Care and Use — Ground-Glass Surfaces

Recommendations for the Care and Use of Glassware

AbrasivesDo not use abrasives on glassware, particularly volumetric ware. The surface will be marred in time, and the resultant scratches may prevent proper drainage or act as resting places for adulterants which will be difficult to remove.

Water for RinsingWhen preparing a piece of glassware for calibration, rinsing with tap water should be followed by a thorough rinsing with distilled water. Sufficient

Ground-glass joints and stopcocks should never be used when dry. Although ground-glass surfaces seal well without the use of lubricants, it is advisable to lubricate them to prevent sticking and breakage. Ground surfaces must be cleaned prior to lubrication—dust, dirt and particulate

matter may score the surface and cause leakage.Different lubricants are used for these operating conditions:Silicone grease—for high temperature and high vacuumGlycerin—for long term reflux or extractionHydrocarbon grease—for general laboratory use

Lubricating Ground-Glass Joints1. Lubricate joints that must be airtight and when glassware contains

A. TO AVOID SERIOUS AND PERSONAL INJURY, AVOID ABRASIONSAn abrasion reduces the strength of glass, making it more susceptible to breakage under impact and/or thermal shock. Thermal shock may result from sudden changes in temperature or use on either a burner or hot plate. Serious injuries could result if breakage occurs while glass holds heated and/or corrosive liquid.B. RECOMMENDED GLASSWARE CLEANING AND HANDLING PROCEDURESProper Cleaning Procedure1. Washing machines may be used. Support racks on the washer must be well maintained. The support pins should be coated with a nonabrasive material to prevent metal to glass contact and scratching.

material may be deposited on the surface by tap water to cause erratic results, particularly with small items, even though water wets the surface uniformly. Even in ordinary cleaning processes, the use of deionised water is recommended.

Adherent Organic ResiduesNever attempt to remove such residues by the application of direct heat. Permanent strains may be introduced and, what is more important, the calibration of volumetric apparatus may be changed.

strong alkaline solutions.2. Lubricate only the upper part of the inner joint. A properly lubricated joint appears clear, without striations.3. Do not allow grease to come in contact with vapour or liquid and cause contamination.

Lubricating StopcocksSpread two circular bands of grease around the stopcock plug. Insert the plug into the barrel and twist several times until the assembly is completely transparent. Be careful not to use too much lubricant or the bore will become plugged.

2. For manual washing, use only plastic core brushes that have soft nonabrasive bristles. Soft, clean sponges or other wiping materials may be used. DO NOT USE THESE BRUSHES OR WIPING MATERIALS WITH ABRASIVE CLEANERS. Keep them clean. Scotch Brite and similar scouring pads will scratch glass and should not be used.3. Inspect glassware before each use and discard if scratched, chipped, cracked or damaged in any way.4. Many commercial glass cleaners are available. Follow the manufacturer’s directions for the use of these products since some are corrosive and can damage the glass.5. Organic solvents are acceptable cleaning agents when conditions warrant their use.

Recommendations for the Care and Use of NMR Tubes

A. TO AVOID SERIOUS AND PERSONAL INJURY, AVOID ABRASIONS AND

IMPACTSAbrasions reduce the strength of glass, making it more susceptible to breakage under impact and/or thermal shock. Thermal shock may result from sudden changes in temperature or use on either a burner or hot plate. Serious injuries could result if breakage occurs while glass holds heated and/or corrosive liquid. Glass will break as a result of impact. Use care when handling to avoid impacting hard objects, such as spigots,

other glassware, counter tops, etc.B. RECOMMENDED GLASSWARE CLEANING AND HANDLING

EQUIPMENT AND PROCEDURESProper Cleaning Procedure1. Kimble Chase offers several styles of NMR tube washers:KON897033-0003 5-place 3mm Tube WasherKON897033-0005 5-place 5mm Tube WasherKON897030-0005 Single-place 5mm Tube WasherKON459960-0000 Single-place 10mm Tube, Cuvette, and Cell Washer2. Before use, rinse or clean the tube with distilled water and dry properly.3. Empty and rinse reusable tubes as soon as possible after use. Always

properly discard disposable NMR tubes as soon as possible after use.4. Use of a fume hood is recommended when cleaning NMR tubes. Popular cleaning solutions include acetone, distilled water, and methanol or ethyl alcohol, as well as organic solvents. Difficult cleaning jobs may require the use of mineral acid or fuming nitric acid soaks. Final rinses of distilled water or acetone are recommended depending on the intended use.5. After cleaning, properly dry by air or with a nitrogen gas stream.6. Inspect tubes before each use and discard if scratched, chipped, cracked or damaged in any way.7. Clean the outside of the tube in order to prevent introduction of dirt or impurities to the probe or the internal mechanisms of the NMR machine.8. Always store NMR tubes in dry, particle free environments. Improper Cleaning Procedure and Use:1. Never use chromic acid, or any caustic or alkaline solutions with an NMR tube.2. Never dry tubes in an oven for more than 30 minutes at 125ºC.3. Never store tubes in an oven. Excessive heat can cause warpage.4. Never use any tube that does not roll evenly on flat surfaces, or exhibits any physical abnormality.

Improper Cleaning Procedure:1. Do not place metal or other hard objects, such as spatulas, glass stirring rods, or brushes with metal parts, inside the glassware. This will scratch the glass and cause eventual breakage and injury.2. Do not use strong alkaline products and hydrofluoric acid as cleaning agents; they are glass dissolvers and can damage the glassware and eventually cause breakage which can result in injury.3. Do not use any abrasive cleansers, including soft cleansers (i.e. Ajax, Comet, Old Dutch, Soft Scrub, etc.), as these will scratch the glass and cause eventual breakage and injury.4. Do not place hands inside glassware while wearing any jewellery, particularly diamond rings, as these will score the inside of the glassware and eventually cause breakage and injury.5. Do not heat glassware to temperatures (>426˚C) needed to burn out carbon residues. This will result in the introduction of permanent stresses in the glass that will eventually cause the glassware to break resulting in

possible injury.C. AVOID IMPACTGlass will break as a result of impact. Use care when handling to avoid impacting hard objects, such as spigots, other glassware, counter tops, etc.

D. HEATING GLASSWARE1. Use wire gauze when heating over open flame.2. Use either low or medium heat settings when using a hot plate. High hot plate settings will cause excessive localised heating of the glassware and will eventually cause breakage and possible injury.3. Do not heat glassware designated as heavy duty unless recommended by the manufacturer. Even though these items have added mechanical strength, they are more susceptible to breakage from thermal shock when heated.4. Do not allow the contents of the container to boil dry as this may induce permanent stresses that will eventually cause breakage. Discard containers that have been boiled dry.DO NOT evacuate or pressurise unless recommended.E. CENTRIFUGE TUBESRCF values can be significantly reduced if the glass tubes have been scratched or otherwise physically abused resulting in surface damage and lowered glass strength.

Care and Handling of Volumetric Glassware

“To Contain ” versus “To Deliver”Proper use of calibrated volumetric glassware requires that the user be informed whether the ware is a “to contain” or “to deliver” vessel. All Kimble calibrated ware is marked either “TC” or “TD”. When the graduation line denotes the volume contained in the calibrated vessel, the ware is marked “TC”. When the graduation line indicates the volume delivered from the vessel, the ware is marked “TD”. When a vessel is calibrated “TD”, it differs from a “TC” calibrated vessel in that a drainage holdback error, the amount of water required to wet the inner surface of the vessel in contact with the water, is added to the “TC” volume. The “TD” vessel then delivers the same volume as contained in a “TC” vessel. Product descriptions in this catalog usually state the method of calibration used. (The International Standards Organization designation for “to contain” is “IN” and “to deliver”, is “EX”.)

Pipettes Calibrated “To Deliver” (EX)The pipette is clamped in a vertical position and the 3-way stopcock connected to it with rubber tubing. The bent arm of the stopcock has a length of rubber hose attached which can be held in the mouth or connected to a vacuum line. Distilled water at the temperature of the room is placed in the large beaker. The water is stirred before use, care being taken not to introduce air into it. Before making a weighing, the pipette is filled one or more times from the beaker by applying suction through the stopcock, in order to bring the pipette to the temperature of the water. Finally the pipette is filled to about 10 mm above the mark, the stopcock closed, and the beaker removed.

The stopcock now is opened to connect the pipette to the straight vertical tube and the water lowered slowly to the 0 line. During this emptying, the edge of the tip is kept in contact with the side of the beaker. The rate of descent of the water is controlled by a finger applied to the upper end of this tube. After setting to 0, the stopcock is closed. Then the temperature of the water in the large beaker is taken and this reading is used as the temperature of the water in the pipette. All deliveries should start at the 0 line.

To start the delivery into the receiver the stopcock is opened fully, again connecting pipette and vertical tube. The plug is not touched after this, any control needed being exercised by the forefinger on the vertical tube. The same precautions are taken as for burettes against splashing of water and wetting the upper part of the neck of the receiver.

Where delivery of a measuring or serological pipette is very rapid, the forefinger must be held on the vertical tube from the start of delivery, but water is retarded as little as possible without losing control. For weighings of intermediate lines, water is allowed to empty until a few mm above the line. Then a finger on the vertical tube is used to slow up the delivery so that the water can be set accurately at the mark. The tip is kept in constant contact with the receiving vessel throughout the delivery. Then the receiver is withdrawn and the stopcock closed. When the pipette has an opaque ring or rings near the top, this indicates that the amount of water remaining in the tip after free delivery has ceased is to be blown out and added to the original delivery. A count of two seconds is made after free delivery has ended and while the neck and tip are still in contact, then air is blown through the rubber hose on the bent arm of the stopcock to eject the liquid in the tip. The neck of the bottle is removed from contact immediately after this. Give only one puff, strong enough to expel the liquid. The time of two seconds has been selected as being the average length of time required in actual service after free delivery has ceased to insert the top of the pipette in the mouth preparatory to blowing through.

Pipettes Calibrated “To Contain” (IN)If the capacity is from a mark to the tip, the pipette should be weighed dry, filled with water to the mark and reweighed. To hold the pipette a saddle may be used on the balance pan. The pipette may be set up as explained previously and the filling and setting to the mark accomplished in the same way. Then, a rubber cap or a piece of rubber tubing closed by a short glass rod is slipped up over the tip and the pipette is removed from the stand and weighed. The first weighing of the dry pipette should include the rubber cap or rubber tubing.

When the indicated volume is between marks, the pipette is filled completely up to the top mark, weighed, dried and then filled up to bottom mark and weighed. The difference in weight is the apparent weight of the water contained between the two marks. In this case the weight of the empty pipette is not needed.

Flasks and Cylinders Calibrated “To Contain” (IN)Flasks and cylinders calibrated to contain are cleaned, dried and weighed empty, filled accurately and weighed again. The difference between the two weights, of course, is the apparent weight of the volume contained.

found best to weigh the filled piece first, empty it and weigh again. The second weight includes the film remaining on the walls after delivery. In all cases, the top of the flask or cylinder should be closed by a cap of some type to minimise evaporation losses. Care must also be taken in handling not to deposit moisture or grease from the hands on the surface of the glass. Therefore, the actual contact with the glass should be by means of a clean cloth, gloves or secure holding device. The entire neck of a flask is wetted by the distilled water and a drainage time of about 2 minutes allowed before completing the setting. To fill a cylinder, the water is allowed to run down one side only, although the entire wall is wetted for about 10 mm above the line to be calibrated by rotation or slightly tipping in several directions. A drainage time of about 2 minutes is allowed before the final adjustment is made. For the final adjustment, a pipette or dropper with a finely drawn point should be used. The temperature of the water can be taken in the filled piece just after the weighing has been completed unless the volume is small. In the latter case, if the thermometer happens to be at a different temperature, the reading obtained may be in error due to the effect of the comparatively large bulk of the thermometer in heating or cooling the water. The alternative is to fill the flask from a reservoir and use the temperature of the water in the reservoir. To calibrate centrifuge tubes, Babcock test bottles and similar articles by weighing the water contained, use the methods outlined for flasks and cylinders, except that the wall is wetted above the line being checked only far enough to insure a correctly shaped meniscus.

FILLING AND EMPTYINGThe results obtained with volumetric apparatus depend not only on the accuracy with which the ware is calibrated, but also on the method of use. Insofar as possible, users should manipulate the instruments in exactly the same way as the manufacturer does when locating the calibration lines. The instructions given here apply particularly to apparatus used with a liquid which wets the glass and must be followed in every respect to obtain the most accurate results when such apparatus is to be calibrated. Since mercury does not wet glass, the factors of importance are cleanliness, the use of an ascending meniscus when possible, and the tapping of the vessel before reading the meniscus.

The following rules have been suggested by the National Bureau of Standards. (These requirements may seem at times to be unduly detailed, but they are based on exact knowledge of the behavior of the various types of apparatus as determined experimentally.)

BurettesBurettes should be held in a vertical position and filled to about 10 mm above the 0 line. Any liquid on the outside of the tip is removed at this

time with clean filter paper. The setting to the 0 line is made by slowly emptying the excess liquid into a beaker or other receptacle with the side touching the edge of the tip. Any liquid remaining at the tip after setting has been made is touched-off against the wet side of the receptacle. When delivery is started, stopcocks should be completely open, even though it is necessary to slow the delivery near the end of a titration. If an exact quantity is desired, the liquid is slowed down when it is about 10 mm above the final line in order to set the meniscus accurately at this line. As soon as delivery has been completed the tip is touched to the side of the receiver and the latter removed from contact. Measurements made in laboratories with burettes ordinarily are from the 0 mark. Other initial points may be used on precision apparatus without serious error, but this is not advised with burets having very rapid delivery.

CylindersIn filling a cylinder the liquid is allowed to flow down one side only. However, the entire wall is wetted for about 10 mm above the meniscus, by a gentle rotation of the cylinder or, preferably, by tipping it slightly in several directions. Here, a drainage time of about 2 minutes is allowed before completing the setting. The delivery of the contents of a cylinder is accomplished in the same way as described for a flask.

(NOTE: These directions apply when highly accurate deliveries are wanted. In ordinary laboratory work where measurements are of approximate volumes only, no special precautions in filling and emptying cylinders are necessary.) You should bear in mind, however, that the accuracy you achieve is dependent on your method. Good method, consistently applied, will yield good results. Poor or sloppy methods will yield poor results.

FlasksWhen a solution is made up to a definite strength in a volumetric flask, the entire neck usually is wet at the time the volume is adjusted, due to the mixing process. Consequently, in filling flasks the entire neck is wetted by the distilled water. A drainage time of about 2 minutes is allowed before completing the setting.If a flask is calibrated to deliver its indicated capacity, the delivery is made by gradually inclining the flask, avoiding, as much as possible, agitation of the contents and sloshing around of the liquid. The process should take half a minute. At the end of the emptying the instrument should be nearly vertical and should be held so for another half minute. Then the drop adhering to the lip should be touched off against the wet surface of the receiving vessel.

PipettesPipettes also are held in a vertical position and filled to about 10 mm

above the 0 line. The technique of setting to this line is the same as used for burettes. The rate of outflow at this point is controlled by slight pressure of the forefinger on the top. With MEASURING and SEROLOGICAL PIPETTES, delivery is unrestricted, unless the liquid descends so rapidly that it would be impossible to stop at the desired place. In this case, however, delivery should be as fast as possible while retaining control with a finger. The tip is touched to the side of the receiver when delivery is completed and then removed immediately, except for certain types of serological pipette. These are “calibrated for blowout”, i.e., to deliver the indicated capacity when the small amount remaining in the tip after free delivery has ceased is blown out (with tip in contact with the wet side of the receiver, if possible) and added to the initial volume. As mentioned before, all blowout pipettes are marked with either a wide opaque ring, two narrower opaque rings near the top, or two printed rings near the top.

(NOTE: With measuring pipettes of small capacity, there may be a tendency for free delivery to cease before the liquid reaches the lowest graduation lines. If this is so, the tip should be kept in contact with the receiving vessel during the delivery, and not just to touch off the last drop when delivery is finished.)

VOLUMETRIC PIPETTES are held in a vertical position and outflow is unrestricted. The tip is touched to the wet surface of the receiving vessel and kept in contact with it until the water has ceased to flow. A count of two is made and the tip then withdrawn horizontally from contact with the receiver. The water remaining in the tip is not blown out, except in the case of Ostwald pipette used in biochemical work. These pipettes are usually “calibrated for blowout” and are marked also with an opaque ring near the top.

Physical Properties of Glass

Glass is an inorganic product of fusion that has cooled to a rigid condition without crystallising and, therefore, has no melting point as such. There are, however, four temperatures that are of interest to the glassblower. They are:

1. The Working Point — the temperature at which glass has a viscosity of 104 poises. At this temperature, glass is soft enough for most lampworking or sealing operations.

2. The Softening Point — the temperature at which glass has a viscosity of 107.6 poises. In this temperature range glass will deform noticeably under its own weight: ASTM C 338.

3. The Annealing Point — the temperature at which the internal stress caused by rapid cooling from lampworking or forming temperatures may be substantially removed in a matter of minutes. It is determined by measuring the elongation rate versus temperature of a fiber of glass under conditions prescribed by ASTM Designation C 336. The values given herein are typical for production glasses.

4. The Strain Point — the temperature at which the internal strain in a glass is substantially relieved only after a matter of hours and not at a commercially desirable rate. It is determined by extrapolation of annealing point data for fiber elongation: ASTM C 336.

is the symbol used to designate “standard taper” interchangeable joints, stoppers and stopcocks, complying with the requirements of ASTM E675 for stopcocks, stoppers and reagent bottle necks and E676 for interchangeable joints. All mating parts are finished to a 1:10 taper.

The size of a particular piece appears after the appropriate symbol. Due primarily to the greater variety of apparatus equipped with fittings, a number of different types of identifications are used, as follows: Apparatus and Bottles• For joints - a two part number, as 24/40, with 24 being the

approximate diameter in mm at the large end of the taper, and 40 the axial length of taper, also in mm.

• For bottles - a single number, as 19, with 19 being the approximate diameter in mm of the opening at top of neck.

• For glass stopcocks - a single number, as 2, with 2 being the approximate diameter in mm of the bore or bores through the plug.

Flasks• For volumetric and Erlenmeyer flasks, graduated cylinders, etc.

a single number as 19, with 19 again being the approximate diameter in mm at top of neck; however, there are differences in dimensions between the bottle and flask stoppers, see the individuals listings in this catalogue.

is the designation for “spherical (semi-ball) joints” complying with ASTM E677.

The complete designation of a spherical joint also consists of a two part number, as 12/2, with 12 being the approximate diameter in mm of the ball and 2 the bore in mm of the ball and the socket.

is the symbol used to designate “product standard” compliance. Kimble glass stop cocks with plugs made of PTFE meet the requirements of ASTM Specification E911. The symbol is used to designate that Kimble stopcocks comply with this standard. All mating parts are finished to a 1:5 taper.

Finally, for the PTFE plug ware, a single number is used, as with stopcocks. Thus, 2 means a stopcock with a bore of approximately 2 mm in the plug.
