The Benchmark Scientific mini-centrifuge includes two rotors and six adapters and it spins samples at 6 600 rpm (rotations per minute) making it suitable for a variety of micro sample sizes and protocols in the research lab. It comes with two interchangeable rotors. The first is a fixed-angle six-place rotor for use with 1.5/2.0 mL micro tubes. The second is a PCR (polymerase chain reaction) strip tube rotor for use with either 2 x 8 PCR strips or 16 x 0.2 mL tubes. Additional adapters (6) are also included for 0.4 - 0.5 mL tubes. All tubes are sold separately. The centrifuge accelerates to its maximum 6 600 rpm then decelerates and stops within seconds for efficient operation. It has a clear see-through lid for observing samples during the spin cycle and an electronic safety cut-off that de-activates the centrifuge when the lid is opened. The mini-centrifuge is used for cell culture applications and separating cell lysates in a research laboratory.The Benchmark Scientific BSC1006
