The continuous flow centrifuge rotor device has the beneficial effects that the device is sterile so as to prevent the separated material from being polluted by the external bacteria, the capacity is high, the rotating speed and relative centrifugal force are high, the centrifugal effect is high, a liquid inlet and drain device is a static assembly, the service life of the liquid inlet and drain device is prolonged, the liquid inlet, centrifugation, and the draining are conducted continuously and simultaneously, and the efficient preparation is achieved.

Description

technical field [0001] The invention relates to the technical field of centrifugation, in particular to a continuous flow centrifuge rotor device and centrifugal equipment. Background technique [0002] A centrifuge is a machine that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid. The centrifuge is mainly used to separate the solid particles in the suspension from the liquid, or to separate two different densities and immiscible liquids in the emulsion. The continuous flow centrifugal rotor is used in high-speed refrigerated centrifuges to achieve continuous separation of a large number of samples: through the strong centrifugal force, negative pressure and height difference between the inlet and outlet liquids generated by the high-speed rotation of the rotor, efficient preparation is achieved. The existing centrifuge rotor has the following problems: the centrifuge rotor will allow air to enter, causing extern...

AI Technical Summary

Problems solved by technology

The existing centrifuge rotor has the following problems: the centrifuge rotor will allow air to enter, causing external bacteria to contaminate the separated material; the liquid inlet and discharge device will rotate together with the rotor, which will greatly shorten the service life of the liquid inlet and discharge device and increase Large damage; the capacity of the centrifuge rotor is relatively small, the speed and the maximum relative centrifugal force are insufficient, resulting in poor centrifugation efficiency and quality; the centrifuge rotor cannot achieve liquid inlet, centrifugation, and liquid discharge at the same time. The order of drainage after centrifugation greatly affects the centrifugation efficiency
