The Z233 M2 microcentrifuge has been designed to provide total control over operating parameters. A microprocessor, brushless induction drive, high speed capabilities, and unmatched capacity make the Z233 M2 the ultimate in high performance. Operating parameters, including speed/g-force and run time are set using easy to turn knobs while their values are shown on large digital displays. Both rpm and g-force can be displayed during a run. Acceleration and deceleration rates can be set at fast or slow. Momentary spins are achieved by pressing the quick button.
