Getting the Centrifuge You Need: Part 2

Choosing a centrifuge compatible with volume of production and specific application needs will ensure more dependable performance and endurance. The choice of materials and features will influence its durability and functionality as well.

Which Model is Right for Me?

Microcentrifuges are used in genomics, molecular biology, biochemistry, and pharmaceutical studies. These units handle micro-volume protocols for DNA/RNA isolation and purification, filtration separations and concentrators, and PCR. They also perform bacteria, yeast, and virus pelleting, virus isolation, and cellular components studies.

 Cole-Parmer-Centrifuge,-4x50mL-Swing-Bucket-RotorPre-clinical centrifuges do mammalian cell pelleting and cell lysate clarification and isolate subcellular organelle/plasma membranes, among other applications.

Small benchtop centrifuges harvest stem cells and accomplish nearly all of the same functions as microcentrifuges.

Similarly, general-purpose centrifuges offer more power, with vastly higher rpms (up to 17,000), yet mimic small benchtop centrifuges in their capabilities. In addition to handling nearly all of the same applications, they also handle mammalian cell pelleting and cell lysate clarification, isolate subcellular organelle/plasma membranes, process tissue and cell cultures, and are used in cell toxicity studies.

Large-capacity centrifuges process larger volumes and maximize productivity. Use these centrifuges for tissue and cell culture processing, stem cell harvesting, cell harvesting, bacteria, yeast, and virus pelleting, virus isolation, bioproduction, and vaccine production.

Other specialty centrifuges are available for food processing, agricultural chemicals, water analysis, sediment determination such as biofuel and petroleum testing, and fat analysis.

While this list is not exhaustive, it provides solutions for most laboratory applications. Ultracentrifuges spin rotors at very high speeds for uses including characterizing proteins. These units require special rotors and may have a limited lifetime.
