CyBio Well vario Maintenance & Care
The piston sealing components are subject to strong wear and tear, conditional upon the
number of motion cycles completed. Typically, their service life exceeds 250 000 cycles. For
this specification, it is assumed that pistons and seals are free from contamination.
9.2.2 Lubricating Transport Rails (Linear Transporting Unit)
1. Remove carriage
2. Grease rails with ultra-thin layer of silicon lubricant
3. Wipe redundant lubricant off
4. Mount carriage
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 assemblies under
mechanical strain and initiate necessary replacements promptly on identifying 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 affected tips will
reach an excessively high fill level. There is danger of pistons coming into contact with liq-
uid and suffering contamination in such cases. This may happen if liquid is drawn from ves-
sels 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-posi-
tion. Repeated faulty operation may lead to excessively high fill levels and a situation of
the kind as described above.
9.2.5 Replacement of Capillaries
Toolset
A set of tools is available for replacement of capillaries or adjustment of their glass tips
( 119 ).
TIP
Dirt, e.g. dried-on liquid, may increase wear dramatically in some cases. Always main-
tain clean working conditions!
TIP
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!
TIP
Before system down-times of several hours or several days, the tips should be un-
clamped. The tip magazine must remain installed in any such case.
