Continuous centrifugal sample injection flow distribution device

Abstract

The invention discloses a continuous centrifugal sample injection flow distribution device which comprises a device body and needle valves. A groove and a plurality of needle valve holes are formed inthe device body, liquid distribution pipes and liquid outlet connectors are arranged on the device body, the groove is formed in the center of the device body, the needle valve holes are axially formed in the upper end surface of the device body, and the liquid outlet connectors are radially arranged on the circumferential surface of the device body; the lower ends of the needle valve holes are communicated with the liquid outlet connectors via the liquid distribution pipes, liquid distribution grooves are formed in positions between the needle valve holes and the groove, the groove is communicated with the lower portions of the needle valve holes via the liquid distribution grooves, and the needle valves are mounted in the needle valve holes. The continuous centrifugal sample injection flow distribution device has the advantages that the sample adding precision can be improved by the aid of the continuous centrifugal sample injection flow distribution device, imbalance due to sampleadding in continuous flow centrifugal procedures can be reduced, and accordingly centrifugal procedures can be stably carried out.

Description

technical field [0001] The invention relates to a continuous centrifugal sample feeding and splitting device. Background technique [0002] A centrifuge is a device that separates substances of different densities in a liquid through the centrifugal force generated when the rotor rotates at high speed. When automatically adding samples to the centrifuge tubes (centrifuge bottles) in the rotor during continuous flow centrifugation, it is usually impossible to accurately make the amount of sample added to each centrifuge tube (centrifuge bottle) the same, resulting in uncontrollable imbalance in the centrifugation process , resulting in increased vibration and noise of the centrifuge, affecting the centrifugal effect. Contents of the invention [0003] The present invention mainly overcomes the deficiencies in the prior art, and proposes a continuous centrifugal sample feeding and splitting device, which solves the problem of uneven sample feeding when a small amount of sam...
