A high-speed centrifuge that can attain revolving speeds up to 85,000 rpm and centrifugal fields up to 500,000 times gravity. The machine is used to sediment (i.e., cause to settle out) and hence separate macromolecules (i.e., large molecules) and macromolecular structures in a mixture/solution. In general, a centrifuge is a machine that whirls test tubes around rapidly, like a merry-go-round, to force the heavier suspended materials (in the solutions in the test tubes) to the bottoms of those test tubes before the lighter material.
High-speed centrifuge (machine to separate particles or media) with rotation fast enough to cause viruses to settle out, even in plasma; used in many forms of biochemical analysis to separate and measure proteins and viruses.
A centrifuge that works at extremely high speeds of rotation: used for separating large molecules, such as proteins.
A high-speed centrifuge capable of producing centrifugal forces more than 100,000 times gravity; it is used in the study of proteins, viruses, and other substances present in body fluids.
