 What is a centrifuge

A centrifuge is a device that can separate substances from the mixtures. In the centrifuge, materials get rotated around a fixed axis by the centrifugal power. A centrifuge can be used in industrial field, chemical field and some other fields. There are several different types of centrifuges, such as industrial centrifuge, haematicrit centrifuge, mini centrifuge and other types of centrifuge.

 What is the working principle of a centrifuge

The working principle of a centrifuge is to use sedimentation principle, which means to move substances outward in the radial direction through the centrifugal acceleration. Because different kinds of substances have different acceleration speeds, they will have different movement trails.

 What is the process of centrifugation

In the process of centrifugation, the materials get rotated powered by the centrifugal power and substances within the materials will have different acceleration speeds, which means substances will get different movement trails. Under the same centrifugal power, different kinds of substances have different sedimentation coefficient. Therefore, some kinds of substances get moved outward. What’s more, different coefficients means substances fall at different time. And that is the process of centrifugation and how different kinds of substances get separated.
