Multiple swing-out and angle rotor options make the Z400 series of high capacity centrifuges useful for a wide range of applications from molecular and cellular biology to microplate technology and blood separations. Maximum speed 13,500rpm/17,310 x g Automatic soft stop braking Microprocessor control with g-force conversion program Multiple swing out and angle rotor options The microprocessor based controls are designed for quick and easy programming of your centrifuge. Parameters are set with knobs while their values are shown on large digital displays. To prevent accidental change, the knobs are inactivated during a run unless the preset key is depressed. The Z400 features maintenance-free, induction drives for exceptionally quiet and smooth operation. Safety features include an electronic lid lock, imbalance sensors and a rotor recognition program that automatically limits each rotor to its maximum rated speed. G-force conversion software allows for setting and display of speed in rpm or RCF. Acceleration and deceleration rates can be set at fast or slow. A continuous flow of ambient air through the rotor chamber of the Z400 prevents sample temperature from rising significantly above ambient, even during extended runs.
