1, centrifugal separation principle

Instrument during the work and produce centrifugal force, because the settlement of centrifugal force lead to action to make the substance of suspended in liquid form precipitation, major material than to turn in the direction of the largest radius mobile, and the proportion of the lighter material deposit on the proportion of heavy material on, make the different proportion of material layer to isolated.

2, the centrifugal force calculation

Separation by centrifugal force is relatively (RCF) of the decision, and the centrifugal force is by speed N (r/min) and the centrifugal radius r (cm) to

3, centrifugal time determination

The same the centrifugal force, centrifugal time and in the separation test solution specific gravity is inversely proportional to the differences, material separation of significant than short time, a small proportion of the separation of the time long.

The same material, separating time and inversely proportional to the centrifugal force, the centrifugal force, centrifugal time is short. The centrifugal force is small, the centrifugal time long.

The same the centrifugal force, centrifugal time and minimum centrifugal radius about. Longer hanging basket (try bottle) need longer centrifugal time. So separating time difficult to calculate, general by test to decide.
