Fixed-angle and swing-bucket rotors with bucket
Period of use
The service life of a rotor/bucket depends on different parameters like care, material and of course on
the factors type and scope of runs.
Eppendorf rotors and buckets have a max. period of use of 7 years from initial commissioning.
No fixed-angle rotors have any restriction on period of use with the exception of F-34-6-38 and T-60-11.
Please follow the instructions in the operating manual and the rotor supplement sheet with specific
reference to measures for looking after rotors.
Once period of use has expired, rotors and buckets should be decommissioned at once!
Visual check/cleanliness
Examine rotors/buckets for dirt residues and check that they have a smooth, clean surface. The
Eppendorf markings should be clearly legible. The bores of the fixed-angle rotors should be checked
with the torch for deposits and for residues of chemicals (use an endoscope if possible).
Aluminum rotors are protected against common laboratory chemicals by an anodized coating. No traces
of corrosion from chemical or mechanical effects, such as falls, blows, scratches, cracks and damage
which may be due to glass from broken tubes not having been removed may be present.
Also check for deformation.
For Rotor A-4-62 with MTP carriers only: ensure that there are no traces of abrasion on the rotor caused
by careless insertion/removal of MTP carriers (not guided in straight).
Rotor cone and motor shaft
Clean with a clean, grease-free, damp cleaning cloth and then dry.
Note: do not use pivot grease.
Perform a visual inspection (using torch if necessary). Check for score marks which can be caused only
by the customer not securing the rotor properly with the rotor key.
Rotor and motor thread
Assess the thread of the motor shaft of the centrifuge (use torch if necessary). Check that the rotor can
be tightened up properly clockwise using the rotor key so as to test the rotor nut as well. After the rotor
nut has been turned through approx. two revolutions, the threads must mesh and it should no longer be
possible to take off the rotor. Turn the nut right in up to the stop and check that it is properly and firmly
located.
Note: do not use pivot grease.
