1. DIRECTIONS FOR USERS

1.1. Safety Instructions
Not all the safety problems that might occur during use of
the dispenser can be covered by this operating manual.
The user themselves are responsible for safe and harmless
practices during use of the dispenser.
When dispensing caustic, toxic, radioactive or health-
damaging chemicals, the utmost care must be taken at
all times.
· Follow general safety rules (e.g. wear protective
clothing, eye protection and protective gloves etc.)
· Observe all the specifications of the reagent
manufacturer.
· Before use, every user must read the operating manual
carefully and comply with it.
· Only use the instrument for its intended purpose and
within the limits of its material resistance (see Application
Exceptions). In cases of doubt about the suitability of the
instrument, always contact the manufacturer first.
· Check the tightness and operation of the instrument
every time before using it. Before initial use, carefully
check that the insert connections are firmly seated, e.g.
tubes etc. Do not use force. Breakage of parts can result
in risk to the user or others.
· Never move the piston while the drip-catcher is on the
tube.
· Carefully pull up the piston and gently press it down.
Do not use force. This applies particularly in the case of
sticking parts. In the event of any problems (e.g. piston
difficult to move), stop dispensing immediately and clean
the instrument (3.1.).
· Avoid any risks to yourself or others. The discharge tube
must always be pointing away from the user and from
any other persons. Avoid splashes. Only use suitable
containers.
· As long as the discharge tube is closed and/or the lever
(12) is set to Locked ( ) , the piston must not be pressed
down. The discharge tube must not be removed during
dispensing or while the dispensing cylinder contains
liquid.
· Since reagent can accumulate in the drip-catcher,
regular cleaning is essential.
· Prevent small bottles or containers from tipping over.
If necessary use a bottle stand.
· Use only original spare parts and accessories from the
manufacturer.
· Do not carry the mounted instrument by the top part of
its housing. When carrying it, always grip it by the reagent
bottle and the dispenser.

1.2. Description of Operation
The Dispenser can dispense liquids directly from containers/
bottles. The instrument can be adjusted to various bottles
using the adapter.
When the dispenser is used correctly, the dispensed liquid
comes into contact only with the materials PFA, borosili-
cate glass, FEP, ETFE, PTFE, platinum-iridium and PVDF.
The Dispenser is equipped with a 3-way valve (14):
· Lever (12) to Dispensing (q): The liquid is dispensed from
the bottle.
· Lever (12) to Return ( ): To remove air from the
dispenser, the liquid is returned to the bottle.
· Lever (12) to Locked ( ) : In the STOP function,
the valve is blocked.
The Dispenser can be autoclaved.
1.3. Application Exceptions
The Dispenser is suitable for many liquids, but not for
reagents which attack PFA, borosilicate glass, FEP, ETFE,
PTFE, PVDF (drip-catcher), PP (adapter, housing) or
platinum-iridium, such as solutions containing hydrofluoric
acid, solutions containing or forming solid particles, and
substances catalytically transformed by
platinum-iridium. In the case of non-organic and oxidable
solutions (e.g. Biuret reagent), metal oxides can be
precipitated. Liquids which form deposits can lead to
impairment of the piston (e.g. crystallizing solutions or
highly concentrated alkaline solutions).
The user must make sure themselves that the instrument
can be used for their specific application.
If inflammable media are to be dispensed, ensure that no
static charging of the instrument and the collecting vessels
can occur.
Physical limits:
· Temperature +15 °C to + 40 °C
for instrument and medium
· Density up to 2.2 g/cm3
· Vapor pressure up to 500 mbar.
· Kinematic viscosity up to 500 mm
1.4. Scope of Supply
1 Dispenser, 1 operating manual,
1 quality certificate, 1 assembly tool, 3 PP adapters,
1 intake tube
1.5. Making ready for use
Where necessary, select the adapter that fits the neck of the
bottle and screw it into the dispenser. The adapters supplied
are made of PP. They must not be used if the reagent attacks
PP. Adapters made of ETFE are available as accessories (9.2.).
