Centrifugation

Centrifugation is the laboratory process that separates the components of a mixture by spinning samples at high rotational speed, so that denser particles move outward and settle while lighter fractions stay near the axis. The equipment that performs it, laboratory centrifuges, spans small personal units through floor-standing high-speed machines. Across the Questpair catalogue 5159 centrifugation listings are offered by 23 verified suppliers and distributors in 10 countries. Of those, 94 percent of the listings are used, the remainder new. New, used and refurbished units all appear, from bench instruments to spare rotors, with prices that run across a wide band depending on speed, capacity and whether a listing is a complete machine or a part.
