The FlaskScrubber spindle rack is designed fornarrow-necked glassware such as volumetric flasks,Erlenmeyer flasks, graduated cylinders, Kjeldahl flasks,test tubes, and digestion tubes.

Two sizes of spindles are provided with the washer:twenty-four 1/4" OD and ten 1/8" OD spindles. Twenty ofthe spindles are factory installed: fourteen 1/4" ODspindles and six 1/8" OD spindles. The front fourteenpositions on the spindle rack are threaded with nylonplugs. You can remove the plugs to accommodate theremaining spindles, if needed.

Loading Glassware into theFlaskScrubberTo load glassware onto a spindle, place the glassware onthe spindle and adjust the position by raising or loweringthe spring clip, as shown in Figure 4-4. The outlet of thespindle should be as close to the center of the flask aspossible. Do not allow the glassware to rest on the end ofthe spindle.

Squeeze the spring cliptogether and raise orlower the clip to positionthe glassware properly.

Figure 4-4



Two large and two small glassware holders are suppliedwith each FlaskScrubber. These holders enable you toplace wide-mouth glassware onto the FlaskScrubberspindles. To position glassware in a glassware holder andinstall the holder on a spindle, refer to Figure 4-5 andfollow the instructions below.

To use a glassware holder:

1. Press the glassware into the holder; the clamps shouldspring out and grip the glassware.

2. Loosen the set screw in the hub, as shown in Figure 4-5, and raise or lower the holder to position the spindlenear the center of the glassware. Do not allow theglassware to rest on top of the spindle.

3. Re-tighten the set screw.

holder. Then, turnthe set screw

counterclockwise toloosen the glasswareholder hub. Positionthe glassware holderso that the spindle is

near the center of theglassware. Turn theset screw clockwiseto tighten the glass-

ware holder in place.



Glassware should be loaded so that it does not touch eachother during a wash cycle. The washer has been designedfor quiet operation. To prevent noise and glass breakage,be certain that the glassware does not touch.

Place heavily soiled items toward the center of the racks.Place lightly soiled items in the corners.

The Detergent DispenserYour Glassware Washer is equipped with a detergentdispenser that contains a main wash cavity and aneutralizing solution port, as shown in Figure 4-6. Inaddition, the washer door has a depression where detergentmay be added for use during the first wash of the cycle.

The detergent dispenser opens during the second washcycle, except when the Plastic cycle is selected, which hasonly one wash cycle. If your glassware is heavily soiled,you may want to add detergent to the pre-wash cavity.Refer to the table below to determine which cavities to fill,based on the selected wash choice. You may use either thepre-wash cavity stamped in the washer door or the one onthe lid of the detergent cup.

Do not use combustible solvents in theGlassware Washer. If soiled glasswarecontains flammable compounds, rinse theglassware thoroughly prior to placing theglassware into the washer. Heaters inthe washer are very hot and could causea fire.

Non-foaming powder or liquid detergent formulated forlabware washers, in conjunction with adequate hot water,is vital for obtaining clean glassware. If the water is soft,less detergent may be needed. Too much detergent withsoftened water may cause etching of the glassware. Thisappears as a permanent cloudy film on the glassware.

Fill the main detergent cavity three-fourths full if the waterhardness grains per gallon (GPG) for your water measures0 � 4 GPG (soft water). Fill the detergent cavitycompletely if your water measures 4 GPG or higher(medium to hard water). If you use the pre-wash cavitystamped in the washer door, fill it completely.

To achieve the bestresults with yourGlassware Washer, useLabconco�s Lab-Solutions Detergent.

!!!!

Store detergent in acool, dry place.Immediately replacethe detergent con-tainer lid afterdispensing. If lumpsdevelop due toexposure to moisture,discard the detergentaccording to localregulations.



To open the detergent dispenser, gentlyslide the white tab sideways. If the tab ispulled upward or perpendicular to thedoor, it will break.

Filling the Neutralizing AcidDispenserIf it is necessary to neutralize the alkalinity of thedetergent, a mild or weak acid may be placed in thedetergent cup neutralizing dispenser from which it will bedispensed during the first rinse. If pure water rinse isselected, the last two rinses will be made with pure water.To avoid dispensing neutralizing acid during a pure rinse,more than two rinses should be selected. The dispenserholds approximately 170 ml and should be checked andreplenished as needed. To fill the neutralizing aciddispenser, refer to Figure 4-6 and follow the instructionsbelow.

To fill the neutralizing acid dispenser:

1. Twist and pull up on the cap to remove the round coveron the neutralizing solution port.

2. Fill the cavity with either 1M citric acid or 10%phosphoric acid until the level of the liquid rises and isvisible in the port.

3. Set the dial to read 4 ml.4. Replace the cover.
