12. Cleaning

The instrument must be cleaned in the following situations to assure correct operation:
- immediately when the piston is difficult to
move
- before changing the reagent
- prior to long term storage
- prior to dismantling the instrument
Warning!
The cylinder, valves, telescoping filling tube and discharge tube
contain reagent! Never remove the discharge tube while the
dispensing cylinder is filled. Point the valves and tube openings
away from your body. Wear protective clothing, eye protection
and appropriate hand protection.
For proper cleaning and removal of any deposits in the parts through
which liquids pass, also always completely with draw the piston from
the cylinder after rinsing with a suitable cleaning solution. If nece-
ssary, the parts can also be cleaned in an ultrasonic bath.
1. Screw the instrument onto an empty bottle and empty it com-
pletely by dispensing (Fig. 1). If the instrument is equipped with a
recirculation valve, it must be emptied in both the ‚dispense' and
‚recirculate' settings.
2. Screw the instrument onto a bottle filled with a suitable cleaning
agent (e.g. deionized water) and rinse the instrument several times
by completely filling and emptying it.
- prior to autoclaving
- prior to changing the valve
- regularly when using liquids which form
deposits (e.g., crystallizing liquids)
- regularly when liquids accumulate in the
closure cap
