3. OPERATION
3.1 Mounting and loading rotor
3.1.1 Installation of rotors
Clean the drive shaft as well as the collet with a clean, grease-free piece of cloth. Place the rotor onto the drive
shaft. (See figure below) Take care that the rotor is fully installed onto the motor shaft.
Figure.10
Hold the rotor with one hand and secure the rotor to the shaft by turning the fixing screw clockwise. (See figure 12)
ATTENTION:
Check that the fixing screw is properly installed before each run.
Do not operate the centrifuge with rotors or buckets which show any signs of corrosion or mechanical
damage.
Do not operate with extremely corrosive substances, which could damage the rotor, buckets and
materials.
In case of any questions, please contact the manufacturer!
3.1.2 Loading angle rotors
Rotors must be loaded symmetrically and with equal weight (See figure below). The adapter may only be loaded
with the appropriate vessels. The weight differences between the filled vessels should be kept as low as possible.
Therefore we recommend weighing them with a balance. This reduces the wear of the drive and the acoustic
operating noise.
On each rotor, the maximum load per hole is stated. (It is only allowed to operate e.g. a 12-place-rotor with 2 ,4 or
8 loaded tubes. But the loaded borings must be opposite each other).
3.1.3 Loading swing out rotors
Loading of the buckets / vessels must be made in accordance with figure 16. It is only allowed to operate e.g. a 4-
place-rotor with 2 loaded buckets, with the loaded buckets located opposite to each other and the unloaded
buckets put inside the rotor (See figure below).
In principle, swing out rotors may not be taken into operation until all buckets or racks are put into the rotor.
The sample tubes have to be filled evenly by eye and put into the drillings or tube racks. The weight difference of
the loaded buckets should not exceed 1 g.
