The QBC centrifuge is a compact, low-profile unit measuring less than 13 cm high with its cover down, housed in a sturdy plastic case. The centrifuge incorporates a 20-place rotor mounted to the shaft of a brush-less DC motor. In addition to shock mounting of the motor to minimise vibration, the centrifuge rests on four suction feet for added stability.

A protective metal cover, with threads into the motor shaft, keeps the spinning tubes snugly in place on the rotor. The hinged top lid with safety latch provides a housing or shield around the rotor during operation. Electrical power to the centrifuge is controlled by a momentary on / off power button located on the front desk. Before the motor starts, the top lid must be closed and latched. Once a spin cycle has started, a safety interlock prevents the lid from being opened until the rotor brakes to a stop. The spin cycle is controlled by an electronic timer on the main circuit board (spin time is fixed at five minutes).
