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 11). Please be sure that the rotor is fully installed onto the motor shaft.
Figure 11
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 12).
Figure 13
For safety, always ensure that the rotor fixing screw is tightened before each run,
(see Figure 12).

2.1.2 Loading Angle Rotors

Rotors must be loaded symmetrically and with equal weight, (see Figures 15 and 17). 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).
