NOTE
If the centrifuge does not reach the mentioned RCF values, the maximum
gravitational field must be set and the run time must be extended.
6.2.2.7
Centrifugation with tubes for mineral oil
In the previous ASTM standard, a maximum gravitational field of 800 x g is
required for the centrifugation with tubes for mineral oil. Practically, it is
possible to reach higher RCF-values with the rotor 11165 and the buckets
13113, 13114 or 13116..
CAUTION
The required gravitational field must not be exceeded.
Values above 800 x g increase the risk of glass breakage!
• Use sealing caps (part no. 17107).
