The HSCo HSC-C-RK21TT is a refrigerated high-speed bench-top centrifuge that covers both high speed and large volumes. It spins at up to 21,000 rpm (up to 50,560 × g) with angle rotors for micro tubes up to 100 ml bottles, and swing-out rotors take up to 4 × 750 ml. The chamber holds anywhere from −20 to +40 °C within ±1 °C, the speed holds within ±10 rpm, and the timer runs from 1 minute to 99 h 59 min.
