Microcentrifuges are compact, high-speed laboratory centrifuges specifically designed for processing small-volume samples, typically held in 0.2 mL to 2.0 mL microcentrifuge tubes. These instruments are essential in any molecular biology, genomics, biochemistry, or clinical research lab where quick and efficient separation of small quantities of biological material is required. Despite their compact size, microcentrifuges are capable of generating high relative centrifugal forces (RCF), often exceeding 20,000 × g, making them ideal for high-speed sample preparation.
Microcentrifuges are commonly used for nucleic acid extraction, protein precipitation, PCR reaction cleanup, and cell lysate clarification. Their rapid spin capability makes them perfect for short bursts of centrifugation—often required during DNA or RNA purification using spin columns. In enzymology and protein studies, they are used to remove precipitates or concentrate proteins from dilute solutions.
In everyday lab workflows, microcentrifuges are also useful for briefly collecting samples at the bottom of tubes before analysis or resuspending pellets. They are found on nearly every molecular biology benchtop due to their convenience, speed, and versatility. Many models now feature digital controls, soft-start and soft-stop functions, and optional refrigeration, enabling labs to protect temperature-sensitive reagents or samples during extended spins.
At Wasteless Bio, we offer high-quality, surplus microcentrifuges from reliable manufacturers at a fraction of the cost of new units. Each listing provides key details such as maximum speed (RPM), RCF, rotor type, sample volume capacity, and cooling features. By sourcing through Wasteless Bio, researchers can lower operational costs, extend the life of lab equipment, and contribute to a more sustainable scientific ecosystem through circular procurement practices. Whether used in daily routines or high-throughput workflows, microcentrifuges remain a workhorse in modern molecular research.
