AI Technical Summary

Technical Problem

The existing density gradient centrifugal technology is complex in the sample separation and collection process, cumbersome steps and high operating environment requirements, which is not conducive to the separation and storage of biological samples.

Method used

A density gradient centrifugal sample separation and collection device is designed, including a body, a separation and analysis unit, a recovery unit and a main control unit. The main control unit controls the movement of the sample tank and the density gradient centrifugal samples of different layers enter the sample channel in turn for separation, and receives the separated samples through the recovery unit.

Benefits of technology

It realizes rapid and precise separation of density gradient centrifugal samples, simple operation and short process time, ensuring the accuracy of sample separation to the greatest extent and reducing contamination in the entire separation process, which is conducive to the separation and preservation of biological samples.

Abstract

The invention discloses a density gradient centrifugation sample separation and collection device which comprises a body, a separation analysis part, a recovery part and a main control part. Wherein a sample groove is formed in the body; the separation analysis part is arranged at the top of the body, a sample channel is formed in the separation analysis part, and the inlet end of the sample channel corresponds to the sample groove; the recovery part is arranged at the top of the body and corresponds to the outlet end of the sample channel; the main control part is arranged on the body, controls the sample groove to move towards the separation analysis part so as to enable the density gradient centrifugal samples of different layers to sequentially enter the sample channel for separation, and controls the recovery part to respectively receive the separated density gradient centrifugal samples. Work is controlled by the main control part, so that a density gradient centrifugal sample is separated after quickly passing through the separation analysis part, the operation is simple, the flow time is short, the sample separation accuracy can be ensured to the greatest extent, the pollution in the whole separation process is reduced, and the separation and storage of a biological sample are facilitated.
