2. OPERATION
2.1 Mounting and Loading the Angle Rotor
2.1.1 Installation of Rotors
Clean the drive shaft and the collet with a clean, grease-free piece of cloth. Place the rotor onto the
drive shaft, (see Figure 9). Please be sure that the rotor is fully installed onto the motor shaft.
Figure 9
Hold the rotor with one hand and secure the rotor to the shaft, by turning the fixing nut clockwise.
Tighten the fixing nut with the provided Allen key, (see Figure 10)
Figure 11
ATTENTION: For safety, always ensure that the rotor fixing screw is tightened before
each run, (see Figure 10)!!
2.1.2 Loading Angle Rotors
Rotors must be loaded symmetrically and with equal weight, (see Figures 12 and 13). 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 to weigh with a balance. This reduces
the wear of drive and the acoustic operating noise.
Each rotor indicates what the maximum capacity is per hole. (It is allowed to operate e.g. a 12-place-
rotor with 2 or 4 loaded tubes only, but the loaded borings must be opposite of each other).
Figure 10

OPERATION
© Hermle Labortechnik GmbH Z326_V2.16 13
Figure 12: WRONG Figure 13: RIGHT (4 tubes)
2.1.3 Loading Swing Out Rotors
Loading of the buckets / vessels must be done in accordance, to Figure 15.
It is allowed to operate e.g. a 4-place-rotor with 2 loaded buckets only. The loaded buckets must be
opposite of each other. Make sure that the unloaded buckets are placed inside the rotor,
(see Figures 14 and 15).
In principle, swing out rotors cannot be removed during operation, until all buckets or racks
are placed inside the rotor.
The bolts of the rotor must be greased with the HERMLE Rotorgrease (Order No. 38-5656).
The sample tubes have to be filled evenly, by eye, and set into the drillings or tube racks. The weight
difference of the loaded buckets should not exceed 1.0 g.
ATTENTION!
Swing Out Rotors can be removed during operation, only if all locations are filled in with either
4 buckets or 4 carriers –do not mix up buckets and carriers!!
Figure 14: WRONG Figure 15: RIGHT
ATTENTION!
Do not operate the centrifuge with rotors or buckets that show any signs of corrosion
or mechanical damage.
Do not operate with extremely corrosive substances, which could damage the rotor
and buckets.
In case of any questions, please contact the manufacturer!

OPERATION
14 Z326_V2.16 © Hermle Labortechnik GmbH
2.1.4 Loading and Overloading of Rotors
All approved rotors are listed with their maximum speed and maximum filling weight, in
Table 2: "Permissible Net Weight", (see APPENDIX P. VI).
The maximum load permitted for a rotor is determined by the manufacturer, as well as the maximum
speed allowed for this rotor (see label on rotor), must not be exceeded. The liquid the rotors are
loaded with, should have a max. homogeneous density of 1.2 g/ml or less when the rotor is running
at maximum speed.
In order to spin liquids with a higher density, the speed has to be reduced, according to the following
formula:
Reduced speed nred =
 x max. speed (nmax) of the rotor
Example:
nred = 
 x 4.000 = 3.360 rpm
In case of any questions, please contact the manufacturer!
2.1.5 Removing the Rotor
Completely, untighten the rotor fixing nut (2. screw over the stiff point) and lift the rotor vertically out of
the centrifuge, (see Figures 9 and 10).
