Description

Technical Field

[0001] The utility model relates to the technical field of drug testing, in particular to a culture medium placement tank. Background Art

[0002] When preparing a drug, its effectiveness is determined by its active ingredient's inhibitory or stimulatory effects on cells, bacteria, or fungi. Cells and other cells require culture medium, and most paste-like culture media are typically stored in storage tanks. Currently used storage tanks require the lid to be fully opened to access the medium, making it susceptible to air contamination during sampling. Furthermore, the gasket at the bottom of the tank is inconvenient to remove. Utility Model Content

[0003] The utility model provides a culture medium placement tank to solve the above-mentioned deficiencies in the prior art, solves the problem that the culture medium is easily contaminated, and facilitates the removal of the gasket, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A culture medium storage tank includes a lower tank body, an upper ring provided at the upper end of the lower tank body, an externally threaded ring threadedly connected to the upper end of the upper ring, an upper tank body provided at the upper end of the externally threaded ring, an upper cover threadedly connected to the upper end of the upper tank body, a rounded groove provided on the upper cover, a sampling hole provided at the bottom of the rounded groove, and a sampler inserted into the sampling hole for sampling culture medium during use, thereby preventing contamination of the culture medium. An inner plate is provided in the rounded groove, which seals the sampling hole to prevent contamination of the culture medium.

[0006] The lower tank body is provided with an inner plate, which is penetrated by multiple movable rods. The upper ends of the movable rods are provided with an upper top ring, which is sleeved with a spring. The spring is located between the upper top ring and the inner plate. The upper top ring is provided with a lower cover. The lower end of the lower cover is provided with multiple L-shaped clips, which are buckled with the upper top ring. When removing the lower cover, the upper tank body can be disassembled from the lower tank body. During the disassembly process, since the upper end of the lower cover loses the force, the spring will cause the lower cover to move away from the lower tank body, thereby facilitating the disassembly and cleaning of the lower cover.

[0007] Furthermore, in order to improve the sealing effect between the lower tank body and the upper tank body, a conical prism is formed on the inner wall of the upper ring, and the lower end of the conical prism is the small end.

[0008] Furthermore, in order to improve the sealing effect of the inner penetrating plate, a baffle is provided at the outer end of the inner penetrating plate. The baffle has an arc-shaped structure, and the inner periphery of the baffle acts on the outer periphery of the upper cover.

[0009] Furthermore, in order to facilitate the insertion and withdrawal operations of the inner penetration plate, a pull ring is provided on the baffle.

[0010] Furthermore, in order to seal the lower end of the lower tank body, a lower end cover is provided at the lower end of the lower tank body.

[0011] Furthermore, in order to improve the sealing effect between the lower cover and the lower tank body to prevent leakage of the culture medium, a sealing ring is provided on the outer periphery of the lower cover. The lower end periphery of the sealing ring is a conical structure, and the lower end of the lower end periphery of the sealing ring is a small end. The lower end periphery of the sealing ring acts on the conical prism.

[0012] Furthermore, to enhance the sealing effect between the upper tank body and the lower cover, an inner sealing ring is provided on the inner circumference of the outer threaded ring. The lower end of the inner sealing ring is tapered, with the lower end of the inner sealing ring being the smaller end. The upper outer circumference of the lower cover is tapered, with the upper outer circumference of the lower cover being the smaller end. The lower end of the inner sealing ring acts on the upper outer circumference of the lower cover.

[0013] Furthermore, in order to facilitate the taking of the culture medium, the upper end of the inner sealing ring is set to a conical structure, and the upper end of the inner sealing ring is the small end.

[0014] The advantages of the above technical solution are:

[0015] The utility model can prevent the culture medium from being contaminated when the culture medium is taken out, and operations such as opening and replacing the lower cover are convenient. BRIEF DESCRIPTION OF THE DRAWINGS
