Priming the
instrument
Note:
Before using the instrument for the first time, ensure it is rinsed
carefully and discard the first few samples dispensed. Avoid splashes.
a) Hold the discharge tube and loosen
the stopper cap/screw cap (fig. a).
b) To avoid splashes, hold the discharge
tube orifice on the inner wall of a
suitable receiving vessel.
Allow the piston to rise up approx.
30 mm and push it down rapidly until
the lower stop (fig. b).
Repeat this procedure approximately
5 times until the discharge tube is
bubble-free. A few bubbles up to
1 mm in size are permissible.
