Before using the instrument for the first time, ensure it is rinsed
carefully and discard the first few samples dispensed. Avoid
splashes.
6.1. Instruments with recirculation valve
1.
Remove closure cap and open discharge tube (Fig. 1).
2.
Set valve to ‚Recirculate' (Fig. 2).
3.
For priming gently pull up the piston approx. 30 mm and push it
down rapidly until the lower stop. Repeat this work step until there
are no more air bubbles in the cylinder (Fig. 3).
4.
Turn valve to ‚Dispense' (Fig. 4).
5.
To avoid splashes when priming hold the discharge tube on the
inner wall of a suitable receiving vessel and dispense liquid to
prime the discharge tube until it is bubble-free. Wipe away any
remaining drops from the discharge tube (Fig. 5).
6.2. Instruments without recirculation valve
1.
Remove closure cap and open discharge tube (see 'instrument with
recirculation valve', Fig. 1).
To avoid splashes, hold discharge tube orifice on the inner wall of
a suitable receiving vessel.
