Operating the pipettor

5.1. Volume setting

The volume of the pipettor is clearly shown through the handle display
window. The delivery volume (variable volume pipettors only) is set by
turning the operating button clockwise or anticlockwise (Fig. 4). When
setting the volume, please make sure that:
1. The desired delivery volume
clicks into place.
2. The digits are completely visible
in the display window.
3. The selected volume is within the
pipettor's specified range.
Do not turn the operating button outside
the volume range because it may jam the
mechanism and damage the pipettor.

5.2. Sealing and ejecting tips

Biohit Proline tips are recommended for use
with Biohit Proline pipettors. Before fitting a
tip ensure that the pipettor tip cone is clean.
Press the tip on the cone of the pipettor
firmly to ensure an airtight seal. The seal is
tight when a visible sealing ring forms
between the tip and the black tip cone
(Fig. 5).
Each Biohit Proline pipettor is fitted with a
tip ejector to help eliminate the safety
hazards associated with contamination.
The tip ejector needs to be pressed firmly
downwards to ensure proper tip ejection
(Fig. 6).
Make sure that the tip is disposed of into a
suitable waste container.
