Micro-nucleic acid vacuum centrifugal concentration device and micro-nucleic acid solution concentration method

Abstract

The present application provides a kind of trace nucleic acid vacuum centrifugal concentration device and trace nucleic acid solution concentration method, trace nucleic acid vacuum centrifugal concentration device includes vacuum pan, aerosol suction accessory, centrifugal mechanism and vacuumizing mechanism;Vacuum pan shell wall is equipped with air extraction hole, air extraction hole is communicated with vacuumizing mechanism, and vacuumizing mechanism is used to carry out vacuumizing treatment to the internal environment of vacuum pan;Centrifugal mechanism includes centrifugal rotor, and centrifugal rotor is rotatably arranged in vacuum pan, and centrifugal rotor is used to install trace centrifugal test tube, to carry out centrifugation to trace centrifugal test tube in trace nucleic acid sample;Aerosol suction accessory is arranged in air extraction hole, and aerosol suction accessory is used to adsorb nucleic acid aerosol in the internal environment of vacuum pan.The present application prevents trace nucleic acid sample transition centrifugation loss, prevents nucleic acid sample aerosol cross contamination situation, retains the physicochemical properties of nucleic acid, and obtains high concentration trace nucleic acid solution sample meeting human and paraffin sample gene library quality standard.
