7.1.6 Centrifugation of substances or mixtures of substances with a density higher than
1.2 kg/dm
3
The density of the substances or mixtures of substances must not exceed
1.2kg/dm³ during centrifugation at maximum speed. The speed must be
reduced for substances or substance mixtures with a higher density. The
permissible speed can be calculated using the following formula:
For example: Maximum speed 4000 RPM, density 1.6kg/dm³
If, in exceptional cases, the maximum load indicated on the bucket is
exceeded, the speed must also be reduced. The permissible speed can
be calculated using the following formula:
For example: Maximum speed 4000RPM, maximum load 300g, actual
load 350g
Please contact the manufacturer if you are not sure.
