3.1.4 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).
The maximum load permitted for a rotor, which is determined by the manufacturer, as well as the maximum speed
allowed for this rotor (See label on rotor), must not be exceeded. The liquids the rotors are loaded with should have
a maximum 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 n

Example:

If in case of any questions, please contact the manufacturer!
To determine the relative centrifugal force(RCF/G-force) for a specific adapter, you can calculate per DIN 58 970
using the attached formula:

RCF = 1.117862*10

n: revolutions per minute (RPM)

3.1.5 Removing the rotor

Untighten the rotor fixing nut completely (screw over the stiff point) and lift the rotor vertically out of the centrifuge.
(See figure 9 and 10).
3.2 Lid control

3.2.1 Lid open

After the run, when the lid of the centrifuge is closed, the word "close" (M1) appears in the display "RPM | RCF"
(A-1). Additionally, if there is a rotor in the centrifuge, the word "rotor"(M3) appears as well as the code number of
the respective rotor, which is in the centrifuge system "71" (M4). If there is no rotor in the centrifuge, the word
"rotor" (M3) flashes and additionally the word "no" (M4) appears. By pressing the key "Door Open" (7) you can
release the lid of the centrifuge. As soon as the electromagnetic lid is completely released, the word "open" (M2)
appears. Now you can open the lid of the centrifuge.
Please refer to figure 15 below for reference.
