Key Features Robust and Durable: The high-quality ABS and PC housing and aluminum alloy rotor is robust, wear-resistant, anti-ageing and impact-resistant. Safety Protection: When the lid is opened during operation, it will automatically stop rotating and return to its original state when closed. High Efficiency: The DC permanent magnet motor has high-speed bearings that run smoothly and powerfully, with a maximum speed of 4000 rpm for efficient centrifugation. Precision Centrifugation: The LCD, speed knob (0-4000rpm) and timing knob (0-999min) allow you to precisely adjust and real-time monitor the speed and time required for centrifugation to achieve optimum results. Eight Centrifuget Tubes: Eight 20ml tube sleeves can be applied to 5/7/10 ml centrifuge tubes to meet the need for simultaneous centrifugation of large volumes of mixtures. Application It is widely used in hospitals, blood centres, universities, research institutes, R&D centres, and laboratories. How to Use 1. Add the substance to the lab benchtop centrifuge tube and insert it into the centrifuge head hole respectively. 2. Close the cover plate and turn on the power switch. 3. Press the rotational speed knob to start, and there is an audible prompt. Rotate the speed knob to adjust the speed, and rotate the timing knob to set the timing. The timing starts after the speed reaches the set value. 4. It will stop automatically when the time comes.
