Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a protein extraction centrifuge with a unified taking and placing structure. Background Art

[0002] When extracting proteins from some solutions, a centrifuge is usually used to separate the proteins from the solution. The centrifuge is mainly used to separate solid particles from liquid in a suspension, or to separate two immiscible liquids with different densities in an emulsion. Existing protein extraction centrifuges still have certain defects when used, such as;

[0003] After the test tubes are placed in the test tube racks of existing protein extraction centrifuges, it is inconvenient to remove the test tubes because the exposed portion of the test tubes is small. At the same time, if the test tubes are long, the exposed portion is large, which affects the centrifugation and most of them cannot be taken in and out uniformly. In addition, most existing protein extraction centrifuges can only accommodate test tubes of fixed specifications. If test tubes of other specifications are to be centrifuged, different test tube racks need to be replaced, which is quite troublesome. Utility Model Content
