Simple and convenient to operate, the new mini microcentrifuges feature greater capacity (8 place MCT and 4 place PCR strip rotors), a quick-release rotor system and electronic brake.Once samples area loaded and the lid is closed, the rotor rapidly accelerates to 6,000 rpm, making it an ideal centrifuge for bringing small droplets to the bottom of tubes for micro-filtrations or basic separations. The new mini microcentrifuges come with a 2-year warranty.
