Instrument introduction:Sigma 3-18ks desktop high-speed refrigerated centrifuge has a maximum speed of 18000 rpm and an accuracy of ± 1 rpm. It can set 10 linear and 10 quadratic acceleration / deceleration curves and store 60 time control programs. Fluorine free environment-friendly refrigerant (R134a) is used to precooling the rotating head in the static state, and the temperature of the centrifugal chamber can be accurately controlled during centrifugal operation. It can be equipped with different angle rotors and horizontal rotors, and can centrifuge centrifugal pipes with different capacities with adapters. It has the function of unbalance protection. When the operation is over, there is an error and imbalance, the sound signal will prompt. The brushless variable frequency motor and microcontroller can control the speed, time, temperature and centrifugal force. It is suitable for low-speed centrifugation such as suspension separation and cell sedimentation.
