Stepped inclinable test tube rack

Abstract

The invention discloses a stepped inclinable test tube rack. The stepped inclinable test tube rack comprises a main test tube rack body and a bracket, wherein the test tube rack comprises two side plates which are arranged symmetrically and upper and lower partition plates which are arranged between the two side plates; a plurality of circular holes for placing test tubes are formed in the upper partition plate; two wall plates are symmetrically arranged on the bracket; shaft holes are formed in the same positions of the two wall plates; rotating shafts are arranged at the same positions of the outer sides of the two side plates of the main test tube rack body; the main test tube rack body is arranged between the two wall plates; the rotating shafts on the side plates are arranged in the shaft holes of the corresponding wall plates; elastic tube clamps are arranged at the position, corresponding to the circular holes of the upper partition plate, of the surface of the lower partition plate. The stepped inclinable test tube rack enables the test tubes arranged on the test tube rack to incline along with the test tube rack, substances in the test tubes are prevented from being polluted, liquid is conveniently added into the test tubes, the work efficiency is high, the substances in the tube are convenient to observe, the operation is convenient, the uniform angle of an inclined plane is guaranteed, the production quality is improved, and the stability for placing the test tubes is improved due to the elastic tube clamps, so that the test tubes can be placed in a layering manner and are convenient to use.

Description

technical field [0001] The invention relates to a test tube rack, in particular to a stepped test tube rack which can place test tubes obliquely. Background technique [0002] In the production of biological products or in the process of biological experiments, a large number of test tubes are needed, and the test tubes are placed in test tube racks. In the commonly used test tube racks, the test tubes are placed vertically, and dust or bacteria in the air are easy to fall into the test tubes and cause pollution. The substance in the test tube has a small liquid surface area, which is not easy to observe. When adding liquid or taking liquid, the test tube should be tilted by hand. When using it, the test tube should be taken off one by one by hand. The rack is on the same plane, so it is inconvenient to use. When adding liquid or taking out liquid, you need to tilt the test tube with one hand, and you need to tilt the liquid adder with the other hand to add liquid. Put t...
