Anaerobic microorganism separation device

Abstract

The invention relates to an anaerobic microorganism separation device. The device comprises a shell, a plurality of test tube rotating assemblies rotationally assembled in the shell, a test tube supporting frame matched with the test tube rotating assemblies and used for supporting anaerobic test tubes, a relative rotating assembly capable of relatively rotating to drive the test tube rotating assemblies to rotate, a driving motor used for driving components in the relative rotating assembly to relatively move, and an ice chamber arranged in the shell; and each test tube rotating assembly comprises a concave test tube support used for clamping the bottom of the anaerobic test tubes, an assembly rotating wheel coaxially arranged with the test tube support, and an assembly rotating shaft used for coaxially installing the test tube support on the assembly rotating wheel, wherein the relative rotating assembly drives the test tube rotating assemblies to rotate through the assembly rotatingwheel. The device replaces an artificial tube rolling, can roll a plurality of anaerobic test tubes at the same time, and avoids the problem of uneven coating of a culture medium. The ice chamber isbeneficial to rapid condensation of the melted culture medium with bacteria so as to improve the tube rolling efficiency.

Description

technical field

[0001] The invention belongs to a microorganism separation device, in particular to an anaerobic microorganism separation device. Background technique

[0002] Anaerobic microbial isolation usually refers to the process of separating specific anaerobic microbial individuals from mixed microbial populations under anaerobic conditions by using aseptic methods. It is mainly divided into plate culture method and Hengate anaerobic rolling tube method.

[0003] The plate culture method includes the dilution pour plate method and the plate streak method. Since most of the microorganisms obtained by the plate culture method are distributed on the surface of the medium, they must be operated and cultivated in special equipment such as anaerobic glove boxes and Gas-pak anaerobic tanks. , the plate culture method needs to use equipment to remove or isolate oxygen or use a reducing agent to react to remove oxygen in a sealed container, but the structure of the former eq...
