1. Safety Instructions
This instrument may be used with approved hazardous materials (refer to chemical
compatibility chart), operations, and equipment. This manual does not purport to address all
of the safety problems associated with its use. It is the responsibility of whoever uses this
instrument to consult and establish appropriate safety and health practices and determine the
applicability of regulatory limitations prior to use.
a. Follow the general instructions for hazard prevention and safety regulations, e.g., wear
protective clothing, eye protection and gloves.
b. Observe the reagent manufacturer’s information.
c. Every user must be acquainted with this Operating Manual before operation.
d. Use the instrument only for dispensing liquids, with strict regard to the defined Operating
Exclusions and Limitations. If in doubt, contact the manufacturer or supplier.
e. When dispensing, the discharge tube must always point away from the user or any other
person. Avoid splashes. Only dispense into suitable vessels.
f. Never carry the mounted instrument by the cylinder sleeve or the valve block. Breakage
or loosening of the cylinder may lead to personal injury from chemicals.
g. Never press down the piston when the closure cap is pushed on.
h. Never remove the discharge tube while the cylinder is filled.
i. Use smooth gentle movements to operate the piston upwards and downwards.
j. Use only original manufacturer’s accessories and spare parts. Don't carry out technical
modifications.
k. Before using check the instrument for visual damages. In case of trouble (e.g., piston
difficult to move, sticking valves or leakage), immediately stop dispensing. Clean the
instrument according to the cleaning instructions.

Application and Design
This instrument is designed for dispensing liquids, observing the following limits:
15 to 40 °C of instrument and reagent
vapor pressure up to 500 mbar
density up to 2.2 g/cm3
Materials
When the instrument is correctly used, the dispensed liquid comes into contact with only the
following chemically resistant materials: Borosilicate glass, PFA, FEP, PTFE, Hastelloy; PP
(closure cap).

5
3. Operating Exclusions
Never use this instrument for
Liquids attacking FEP, PFA, PTFE or Hastelloy.
Liquids attacking borosilicate glass (e.g., hydrofluoric acid)
Liquids which are decomposed catalytically by Hastelloy (e.g., H2O2)
Explosive liquids.
Suspensions as solid particles may clog or damage the instrument.
4. Operating Limitations
Concentrated hydrochloric acid and concentrated nitric acid, chlorinated and fluorinated
hydrocarbons or liquids which form deposits may make the piston difficult to move or may
cause jamming. When dispensing flammable media, make provisions to avoid static charging,
e. g., do not dispense into plastic vessels; do not wipe instruments with a dry cloth.
Warning!
If there is a sign of a potential malfunction (e.g., piston difficult to move) never use force.
Immediately stop dispensing and follow cleaning instructions or contact the manufacturer.
Note:
Compatibility of the instrument for this special application (e. g., trace material analysis) must
be checked by the user or contact the manufacturer.

5. Preparing instrument for use
Attention! The adapters supplied with the instrument are made of polypropylene (PP), and can
only be used for media which does not attack PP.

Attention! The adapters supplied with the instrument are made of polypropylene (PP), and can
only be applied to media which do not attack PP.
7. Priming the instrument
Attention! For small bottles use a bottle stand to prevent tipping over.
Warning! Reagent may drop off the discharge tube and closure cap.
Figure 4
Hold the discharge tube and carefully remove the closure cap.
Slide the closure cap backwards on the tube support, away from the discharge tube
opening.
