Maintenance & Care
9.2.3 Cleaning the Lifter
Contamination and natural wear of modules give rise to increased strain levels and,
hence, an increased probability of failure. Check for signs of wear and tear on assem-
blies under mechanical strain and initiate necessary replacements promptly on identify-
ing wear and tear.
Check lifter for dirt at regular intervals. Clean if necessary.
9.2.4 Tip Magazine (Pipetting Head)
Operating the CyBio
®
Well vario in manual or automatic mode, you should carefully
watch for and remove residual air bubbles from the tips. Otherwise, the liquid in affect-
ed tips will reach an excessively high fill level. There is danger of pistons coming into
contact with liquid and suffering contamination in such cases. This may happen if liquid
is drawn from vessels with insufficient filling level or if tips are not introduced deep
enough.
Make sure that pistons cannot come into contact with liquid during motion into zero-
position. Repeated faulty operation may lead to excessively high fill levels and a situa-
tion of the kind as described above.
NOTE
XY-lifter motion must not be obstructed by unwanted objects. Otherwise, the life time
of motors will diminish significantly.
CAUTION
Direct contact of the tip magazine and the pistons may damage the pistons.
Never install a tip magazine without tips into the pipettor! A tip magazine inserted with
no tips installed will void any warranty claims!
NOTE
Before system down-times of several hours or several days, the tips should be
unclamped. The tip magazine must remain installed in any such case.
