2 OPERATION
2.1.2 Mounting and loading swing out rotors
Clean the drive shaft, as well as the location hole of the rotor with a clean and grease-freecloth. Put the
rotor to the motor shaft. Take care thatthe motor shaft is plugged completely in the rotor nut.
Hold the rotorwith one hand and secure therotor to the shaft by turning the rotorscrew (1) clockwise.
The charging of the buckets and the adapters must be doneappropriately photo 10.
In principle swing out rotors may not be taken in operation until all buckets or racks are put into
the rotor.
The bolts at the rotor must be easily greased with silicone grease.
The sample tubes have to be filled evenly by eye andput into the drillings or tube racks. The weight
difference of the loaded buckets should not exceed approx. 1.0 g.
It is allowed to operate e.g. a6-place-rotor with 2 loaded buckets only. But the loaded buckets must be
opposite to each other. Makesure that the unloaded buckets also be put inside the rotor (see photo 9
and 10).
ATTENTION: CLS-EQ-104 October 2013 , Document 01, Revision 02

Swing out rotors may be taken in operation only if all places are filled in with four buckets!!
Photo 9: wrong Photo 10: right
2 OPERATION
2.1.3 Overloading of rotors
The maximum load permittedfor a rotor, which is determined by themanufacturer, as well as the
maximum speed allowed for this rotor (see label on rotor),must notbe exceeded.
The liquids the rotors are loaded with should have an average homogeneous density of 1.2 g/ml orless
when the rotoris running at maximum speed.
In order to spinliquids with a higher density, thespeed has to be reduced according to the following
formula:
1.2
Reduced speed nred = x max. speed (nmax) of the rotor
higher density
Example: CLS-EQ-104 October 2013 , Document 01, Revision 02
