Microcentrifuges:

ompact footprint centrifuges used for small sample sizes, such as microtubes. Ideal for microfilter cell separations and HPLC samples. Available as electronic or handheld manual units; may have digital interfaces and refrigeration capabilities. Microcentrifuges are specifically designed to accommodate tubes that hold less than 5.0 mL. Although benchtop centrifuges can be fitted with rotors for microtubes, microcentrifuges usually have a smaller footprint, which makes for a less-crowded work area. As with other benchtop centrifuges, these units can be ventilated (operated without temperature controls) or refrigerated. Most are sold with a rotor, although additional alternate rotors may be available.
