The Z400 series has multiple swing-out angle rotor options which make it useful to a lot of applications from cellular or molecular biology to blood separations and microplate technology. It has a maximum speed of 13,500rpm and has automatic soft stop brakes. Its microprocessor control comes with a g-force conversion program. Its controls are designed to make programming of the centrifuge quick and easy. Its parameterscomewith knobs with values shown on digital displays. To prevent change, its knobs will be inactivated when it is running unless preset key is pressed. The Z400 has induction drives are maintenance free and provides quiet and smooth performance. For safety, it uses an electronic lid lock, sensors for imbalance, and rotor recognition program which limits the rotors' maximum speed rate automatically. This conversion software called G-force allows the display and setting of speed in rpm unit or RCF.
