Suggestions
Adjust the feet with the help of a screw wrench. Please
work with someone together to carefully tilt the Precel-

Never set the Precellys 24/Precellys
because the weight could damage the casing.
Check the unit is plugged in properly. Make sure that
the power input filter on the back of the device

Lock the tubes properly. Clean and/or disinfect the
system as described in 'CLEANING AND DECON-
TAMINATION'.
Occurs eventually using very small beads (e.g. VK01).
Pay attention that there is no sample material or beads
located at appropriate sites of the cap or tube (option-
ally tubes can be briefly centrifuged).
Use exclusively high-quality screw cap tubes e.g. the
Precellys lysis kits of PEQLAB. By using the larger
beads (e. g. CK28 or MK28) the sample volume
should be at minimum 500 μl (see also 'General user
tips')!
The maximum sample volume of 1.4 ml in the 2 ml
tubes and 5 ml in the 7 ml tubes should not be ex-
ceeded in order to guarantee sufficient compressible
volume for a potential heat expansion in the tube.
Make sure the electrical power supply is working and
turn the system back on. The vacuum is relieved then
and the indented plate can be removed.
