Note:
The clinical centrifuge is calibrated at 120 volts line voltage. Operating the
centrifuge at a line voltage other than 120V can significantly impact the speed settings
below 2,000 rpm.
4. Proper loading of the rotor
4.1 Rotor capacity
The rotor has been designed to handle samples with a maximum density of 1.2g/mL.
Tubes should not be run with any substance having a density above 1.2g/mL.
4.2 Rotor loading
When loading the rotor you should proceed according to sketch A. Fill the tubes equally
by eye and insert them into the tube shields of the rotor. The difference in weight
between the tubes should not exceed 2 – 3 grams.
A partially loaded rotor may be centrifuged. For example, you may operate a 6-place
rotor with 2, 3 or 4 loaded tubes, but it is important that the occupied tube shields are
symmetrically arranged. (see sketch A)
