Continuous flow centrifuge rotor device and centrifuge

Abstract

The invention relates to the technical field of centrifugal, in particular to a sterile continuous flow centrifuge rotor device and centrifuge equipment. The sterile continuous flow centrifuge rotor comprises a sample feeding pipe, a drain tube seat, an isolation sleeve, a sealing cover, a centripetal pump assembly, a rotor body, a rotor core, a transfer pin mounting block and a rotor cover, the drain tube seat is arranged on the sample feeding tube in a sleeving mode, the isolation sleeve is arranged at the lower part of the drain tube seat in a sleeving mode, the sealing cover is arranged atthe lower part of the isolation sleeve in a sleeving mode, the centripetal pump assembly comprises a centripetal pump cover body and a centripetal pump body, the upper part of the rotor core is arranged on the sealing cover in a sleeving mode, the rotor body is arranged on the rotor core in a sleeving mode, and the rotor cover is arranged at the upper part of the rotor core in a sleeving mode. 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...
