Filling centrifuge tubes
1. Open the lid.
2. Loosen the rotor clamping nut using the spanner supplied by turning
it anticlockwise.
🡆 After passing the working point for lifting the rotor, the rotor
detaches from the cone of the motor shaft (
2
).
3. Turn the clamping nut until the rotor can be lifted off the motor shaft.
4. Remove the rotor.

The lid is open.
1. Clean the motor shaft (
2
) and rotor hole.
2. Lightly grease the motor shaft (
2
), see ⮫
Chapter 8.2 ‘Cleaning and
disinfection instructions’ on page 32
.
3.
Place the rotor vertically on the motor shaft (
2
).
The two marker bars (
1
) on the rotor must be parallel to the two
surfaces (
3
) on the motor shaft.
4.
Tighten the rotor clamping nut hand-tight by turning it clockwise using
the hex key provided.
5.
Check that the rotor is îž„rmly seated.
6.
A test run must be performed if a different rotor has been installed.
For the test run, the adjustment weight supplied (7g) must be placed
in a rotor location and a centrifugation run with a runtime of 1 minute
must be performed at a speed of 6000 RPM.
🡆 The drive must not switch off.
The adjustment weight must be removed from the
rotor location again before the next centrifugation
run.

WARNING
Risk of injury from contaminated sample material.
Contaminated sample material escapes from the sample
tube during centrifugation.
− Use centrifuge tubes with special screw caps for haz-
ardous substances.
−
For risk group 3 and 4 materials, use a biosafety system
in addition to the sealable centrifuge tubes (see WHO's
'Laboratory Biosafety Manual').
