0 a machine that turns a container round very quickly, causing the solids and liquids inside it to separate by centrifugal action
This is no doubt related to the increased interest in gas centrifuges as a means of separating uranium isotopes.
The homogenate was centrifuged and the supernatant concentrated to 500 mg/ml as before.
Lysed cells were centrifuged at 2500 g for 15 min and the pellet containing unbroken cells, nuclei, and kinetoplasts was discarded.
After 24 hours, the conditioned medium was harvested, centrifuged to remove cellular debris and protein concentrations determined.
The samples were mixed well with 75 l chloroform and centrifuged for 20 min at 15 000 rpm.
In this method, large membrane fragments are centrifuged at high g forces.
The liquid was decanted into 50 ml centrifuge tubes and the sediment discarded.
The culture was then centrifuged at 25 000x g for 15 min and the supernatant was discarded.
