Laboratory centrifuge basics

Posted by ShopLaboratory on 23rd Feb 2022

Centrifuges are devices used in laboratories, that rotate objects (samples) around a stationary axis at a high speed. In this process, centrifugal force is used to separate liquid components of different densities.

What is the working principle of a centrifuge?

By the principle of sedimentation, high-speed rotation creates the centrifugal force, which allows materials of different densities to be separated. Materials of higher densities settle to the bottom of the sample, while lower density materials float on top. Centrifuges are capable of separating liquids from solids, liquids of different densities, or two different density solids.

How are centrifuges used in laboratories?

Centrifuges may be used in cases when the separation of liquid or gas components is necessary. The separation of components is an important part during diagnostics and analysis, for example, in blood testing – separating blood plasma from red blood cells and platelets. All in all, centrifuges are used for the purification of components of cells, viruses, proteins, and other substances.

  • material (plastic, metal, glass),
  • dimensions
  • number of tubes
  • capacity
  • custom features you may need.

Finally, if you want to be sure of making the right decision while choosing a centrifuge, the best way to do it is to talk to a professional. If you want to consult with a specialist, we recommend writing to our competent support staff at
