1. Safety Instructions
This instrument may sometimes be used with hazardous materials, operations, and equipment. It is beyond
the scope of this manual to address all of the potential safety risks associated with its use in such applica-
tions. It is the responsibility of the user of this instrument to consult and establish appropriate safety and
health practices and determine the applicability of regulatory limitations prior to use.
Please read the following carefully!
!
1. Every user must read and understand this
operating manual before operation.
2. Follow general instructions for hazard preven-
tion and safety instructions; e.g., wear protec-
tive clothing, eye protection and gloves.
3. Observe all specifications provided by reagent
manufacturers.
4. When dispensing inflammable media, make
sure to avoid the buildup of static charge, e.g.,
do not dispense into plastic vessels; do not
wipe instruments with a dry cloth.
5. Use the instrument only for dispensing liquids,
with strict regard to the defined limitations of
use and operating limitations. Observe operat-
ing exclusions (see page 31)! If in doubt, con-
tact the manufacturer or supplier.
6. Always use the instrument in such a way that
neither the user nor any other person is endan-
gered. When dispensing, the discharge tube
must always point away from you or any other
person. Avoid splashes. Only use suitable ves-
sels.

directly from the supply bottle. Available in variable and fixed models.
The instruments are, according to the requirements of the DIN EN ISO 8655-5, marked DE-M.
When the instrument is correctly used, the dispensed liquid comes into contact with only the following
chemically resistant materials: Borosilicate glass, AI
(closure cap). If a higher chemical resistance is required, please use a ETFE/PTFE bottle adapter (‚Accesso-
ries', pages 37).
For dispensing hydrofluoric acid, we recommend the use of the VITLAB

9. Reagents can accumulate in the closure cap
of the discharge tube. Thus, the closure cap
should be cleaned regularly.
10. For small bottles, and when using the
flexible discharge tube, use a bottle stand to
prevent tipping over.
11. Never carry the mounted instrument by
the cylinder sleeve or the valve block. Breakage
or loosening of the cylinder may also lead to
personal injury from chemicals (see page 35,
Fig. 3).
12. Never use force on the instrument. Use
smooth gentle movements to operate the
piston upwards and downwards.
13. Use only original manufacturer's accessories
and spare parts. Do not attempt to make any
technical alterations. Do not dismantle the
instrument any further than is described in the
operating manual!
14. Always check the instrument for visible dam-
age before use. If there is a sign of a potential
malfunction (e.g., piston difficult to move,
sticking valves or leakage), immediately stop
dispensing. Consult the ‚Troubleshooting' sec-
tion of this manual (see page 52), and contact
the manufacturer if needed.
