This Becton Dickinson QBC 424740 hematocrit centrifuge includes the rotor (without built-in reader) with cover as shown here. The QBC Centrifuge is a low-noise, high-speed instrument specifically designed to meet the cell packing requirements of the QBC test method. Up to 20 blood tubes can be spun simultaneously. Nominal speed is 12,000 rpm and relative centrifugal force is approximately 14,387× g. Spin time is fixed at 5 minutes. The QBC Centrifuge is an ultra-compact instrument, designed to spin down blood specimens for QBC Centrifugal Hematology tests or QBC Malaria tests. It's a low-profile unit measuring less than 13 centimeters (5.1 in.) high with cover down, and housed in a sturdy plastic case. The centrifuge incorporates a 20-place rotor, mounted to the shaft of a brushless D.C. motor. In addition to shock-mounting of the motor to minimize vibration, the centrifuge rests on four suction feet for added stability. A protective metal cover, which threads onto 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 deck. Before the motor will start, 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 5 min. A green light emitting diode (LED) for "SPEED" and a yellow LED for "POWER" adjacent to the "ON/OFF" button provide visual indicators of power circuit status. Condition of each LED (On, Off, or Flashing) based on the status of power, lid latching, rotor speed, etc. The QBC Centrifuge is shipped with an external plug-in power pack. FEATURES SUMMARY:
