Laboratory Centrifuges

By spinning at high speed, a centrifuge uses g-force to separate particulates in suspension according to their density. A laboratory centrifuge may be used for sedimentation of cells and viruses or to isolate macromolecules such as DNA. Application areas for centrifuges include biology, biochemistry, environmental, pharmaceutical, and clinical testing.

What Are Different Types of Centrifuges?

General-purpose benchtop or tabletop centrifuges are the most common type, with volume ranges covering 0.2 to 750 mL or so. Refrigerated units, compact mini centrifuges, and high-speed tabletop units with RCFs close to that of floorstanding models are also available. The g-forces of ultracentrifuges, often used in nanotechnology, can top 1,000,000 × g. Microcentrifuges are for work with smaller microcentrifuge tubes and PCR tubes.

What to Consider When Choosing a Centrifuge:

  • RCF is the most important indication of separation power.
  • Rotor types include swinging bucket, fixed-angle, or vertical, in plastic and metal versions.
  • Sample volume and available lab space are also important in determining the size of centrifuge needed.
