Selecting Micro Centrifuge Tubes on Amazon.com

A micro centrifuge tube, also spelled microcentrifuge tube, is used with a microcentrifuge, a piece of lab equipment that spins small volumes of biological molecules, cells, or nuclei to separate components. The device is typically small in size for bench top use, and has a rotor that can quickly change speeds. Micro centrifuge tubes commonly hold 0.5 to 2.0mL of fluid, and are spun at maximum angular speeds of 12,000 to 13,000 rpm. The tubes are made of plastic, such as polypropylene, with a screw cap or an attached cap for preventing spills, and often are stored in a microcentrifuge tube rack. They are typically sterilized using gamma radiation, and have non-pyrogenic characteristics. Microcentrifuge tubes are used for spinning biological samples in medical, industrial, and research laboratories, as well as academic and clinical settings.
