99% of all users look for an uncomplicated dispenser. It’s good fortune that the EM-dispenser is available.

Durable in useDuring dispensing, the glasscylinder is protected completelyby the robust plastic sheathing.The EM-dispenser can also nor-mally withstand bumps or acci-dents without any adverse con-sequences.

Quick exchange of valvesWith the EM-dispensers the suc-tion and dispensing valves canbe simply exchanged by meansof the assembly key (in the stan-dard range). Ideal for cleaningor for exchanging of the valves.

Easy to cleanWith clear liquids which do notcrystallise cleaning is not reallynecessary, simply rinsing isenough. However, if cleaning isrequired, it’s no problem. Thepiston and the valves are remo-ved with a twist of the hand.

Sterilisable without dismantlingWhoever has responsibility forsterility can work with the EM-dispenser at ease and economi-cally. The complete unit –including the dispensing tube –is steam sterilisable at121°C/2 bar.

Thousands of dispensingoperations exact and reliableThe exact setting ring on the EM-dispenser cannot work itselfloose or be misset by accident.Once a volume has been set, itremains locked in position, con-stant over thousands of dispens-ing operations. The componentson the EM-dispenser whichdetermine volume are made ofpractically abrasion free mate-rials. This guarantees accuracyover a long period of use.

Long lifeWhen used with common me-dia, the EM-dispenser demon-strates an extremely long life ex-pectancy. This is no coinciden-ce, as the EM-dispenser consistsof significantly chemically inertand mechanically nearly wearand tear free materials.

Dispensing without compromise – exact volumes,repeatable and reliable.

Suitable for chemical trace analysisTests have demonstrated that themajority of media can be purelydispensed for chemical traceanalysis with the EM-dispenser.Every component which comesinto contact with the medium ismanufactured from a materialwhich is inert against the mostcommon media. The valve blockcontains no colour, the fluor plastic contains no colorants atall or other additives.

12 months guaranteeWe are so convinced of thesuperior quality of our EM-dispenser that you don’t have tobe satisfied with just the statutory6 months.

From 0.2 ml to 60 mlThe EM-dispenser models withvariable volumes cover entirelythe range of customary dispen-sing volumes. Beginning with themodel for 0.2 to 1.0 ml (50 µlincrements) up to the model for10 to 60 ml (1 ml increments).In addition there is for specialapplications with fixed volumesa series of EM-dispensers withfixed volumes.

EM-dispenser – quality atrealistic pricesIt isn’t easy to find a similarly ac-curate, comfortable and robustdispenser as the EM-dispenser.We haven’t considered the priceeither for even if the performan-ce data are unusual, its price is normal ...

Safe suctionThe suction tube of the newgeneration of EM-dispensers isscrew-threaded. Once screwedon, the suction remains perma-nently air-tight.

Ceramic, glass, PTFE and a superior construction principle.

Abrasion and scratching?Not with the ceramicpiston!The pistons in many dispensersare made of fluor plastics or atleast coated with such materials.For the relatively soft andsmooth plastic has the advan-tage of working like a self-grea-sing coating. But, watch out! Theexact seating of the piston canquickly deteriorate through abrasion with the surface of thepiston becoming badly scrat-ched. That’s why Hirschmannuses in its EM-dispenser a pistonmanufactured from an extremelydurable aluminum oxide ceramic. As this ceramic pistonfits into the glass cylinder to a micrometre tolerance, any further coating is superfluous.Even if the piston becomes diffi-cult to move freely due to crystal-lising of disperse media, therewill be no abrasion - simple cleaning suffices.

Softening, break-up? Notwith the ceramic piston!Admittedly the majority of mediadoesn’t directly attack plastics.Nonetheless, they do demon-strate with a series of organicreagents a clear softening effect.In dispensers with plasticpistons, the result can be seizureor flaking of the coating andfinally volume errors. That’s whywith the EM-dispenser only thevolume-uncritical componentsare made of plastics (ECTFE,glass fibre reinforced PTFE). Allthe components which determinevolume, like the piston and thecylinder, are on the other handon the EM-dispenser made ofceramic or glass respectively.

Wear and tear freevalves? with the EM-dispenser naturally!Even the valves of a dispensershould be chemically inert andto a large extent mechanicallywear and tear free. That’s whythe valve bearings and valveseatings on the EM-dispenserare manufactured from groundborosilicate glass.

From 4°C to 50°C? Onlywith the EM-dispenser!The smoothness of operationand accuracy of dispensers withsolid plastic pistons is clearlytemperature dependent. The EM-dispenser may, however, beused without question in terms offunctional safety and accuracyin an extremely wide tempera-ture range. For borosilicate glassand aluminum oxide ceramicare both materials with an extre-mely minute and almost identicalrange of thermal expansion.

Digital setting – withoutadjustmentThe volume to be dispensed is setin a matter of seconds with abso-lute accuracy – any adjustmentis superfluous. Uniquely of all theequipment on the market, theEM-dispenser is equipped with amechanical digital volume set-ting system with an internal stepgauge and an exact setting ring.

Everything under visualcontrolThe protective cover of the EM-dispenser incorporates two clearglass windows. Air bubbles arefor this reason discovered imme-diately.

Splash-free workingDispensing according to the re-gulations, meaning while in con-tact with the inside of the re-ceiving vessel is no problem.The dispensing tube of the newgeneration of EM-dispensers islocated within a stable supporttube.

Even subsequent volume-tric tests are possiblewithout any problemAccording to ISO 9000 theaccuracy of every single volume-tric equipment should be chek-ked at regular intervals. Eventhis calibration test should bedocumented. HirschmannLaborgeräte offers you help in

ISO 9000 demandsexact documentationISO 9000 and the GLP regula-tions demand for the recognitionof a “quality assured laborato-ry“ documentation detailing theaccuracy of the test methodolo-gy and the volumetric equip-ment. Practicability and econo-my therefore suggest that onlydispensers with conformity certifi-cation or better still individuallytested and certified equipmentshould be used. EM-dispenserare fulfilling these requirementswithout any compromise.

With EM-dispensers, the documentation is delivered with the dispenser...Whilst to meet the confirmityrequirements of the test authoritya random test of each produc-tion batch is adequate, the accu-racy of every EM-dispenser isindividually tested. A certificateof this individual test is enclosedwith every dispenser. Each certi-ficate also lists a serial numberwhich is engraved on thedispenser and is clearly trace-able. It can therefore be listed inthe quality documentation accor-ding to ISO 9000 without furthereffort.
