Centrifuge By Praxor Instruments & Scientific Co

Types by intended use: Ultracentrifuges are optimized for spinning a rotor at very high speeds and are popular in the fields of molecular biology, biochemistry and polymer science. This type may include preparative or analytical, fixed-angle or swing head varieties.[3]
Haematocrit centrifuges are used to measure the percentage of red blood cells in whole blood.
Gas centrifuges, including Zippe-type centrifuges
Industrial centrifuges may otherwise be classified according to the type of separation of the high density fraction from the low density one:

Screen centrifuges, where the centrifugal acceleration allows the liquid to pass through a screen of some sort, through which the solids cannot go (due to granulometry larger than the screen gap or due to agglomeration). Common types are:
Screen/scroll centrifuges
Pusher centrifuges
Peeler centrifuges
Decanter centrifuges, in which there is no physical separation between the solid and liquid phase, rather an accelerated settling due to centrifugal acceleration.
Continuous liquid; common types are:
Solid bowl centrifuges
Conical plate centrifuges.
