Technical Field

[0001] The utility model belongs to the technical field of liquid measuring, and in particular relates to a liquid measuring device for test tube liquid culture medium. Background Art

[0002] Liquid culture medium, the counterpart of solid culture medium, is a liquid culture medium for microorganisms or animal and plant cells. It has the advantages of aeration culture and shaking culture. Under static conditions, a barrier to the permeability of nutrients is formed around the bacteria or cultured cells, and the intake of nutrients is hindered. Since this barrier can be eliminated and the oxygen supply can be increased under ventilation or shaking conditions, it is beneficial to cell growth and increase production. When adding test tube liquid culture medium, a liquid measuring device for test tube liquid culture medium is required.

[0003] In the prior art, the liquid measuring device for test tube liquid culture medium generally includes a soft rubber test tube with an opening at the bottom. The opening is generally inserted into the liquid, and then the liquid is sucked by squeezing the rubber head of the soft rubber test tube, and then the liquid is squeezed into the liquid culture medium.

[0004] However, when the above device is used, the soft rubber test tube relies on squeezing by human fingers to complete liquid absorption, which makes it difficult to quantitatively absorb the liquid and easily causes excessive or insufficient addition. Utility Model Content

[0017] The utility model is further configured that a pressure pad is fixedly connected around the pressure plate, and the pressure pad contacts and slides with the inner wall of the tube body, and the pressure pad is made of rubber material and has a double-layer cavity structure.

[0018] Through the above technical solution: the design of the double-layer cavity structure can increase the deformation capacity of the pressure pad, and at this time, it can prevent the liquid from leaking through the gap between the pressure plate and the tube body.

[0019] The utility model is further configured that a feed port is opened on one side of the top outer wall of the tube body, and a sealing plug is inserted into the inner wall of the feed port.
