Multiple swing-out and angle rotor options make the Z 400 series centrifuges useful for a wide range of applications from molecular and cellular biology to microplate technology and blood separations.The microprocessor based controls are designed for quick and easy programming. 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. A continuous flow of ambient air through the rotor chamber of the Z 400 prevents sample temperature from rising significantly above ambient, even during extended runs.

The powerful refrigeration system in the Z 400 K can maintain all of the available rotors at or below 4°C, even at maximum speed.
