The Sorvall RT6000B refrigerated centrifuge features a see-through chamber door that allows rotor calibration and visual inspection of a run in progress. The rotor chamber lid is counterbalanced for easy opening and safe closing. The lid latch is locked manually by turning the door release knob counter clockwise, then spinning preventing the chamber lid from being opened during operation. In addition, a slow-start feature allows slow, smooth acceleration from 0 to 500 rpm
