Press-out leakage-proof increased anti-skid easy-to-press surface sampling culture dish

Abstract

The invention discloses a press-out leakage-proof increased anti-skid easy-to-press surface sampling culture dish. The culture dish comprises a dish bottom and a dish cover, and the dish bottom is provided with a second buckle and a first buckle which are of a stable embedded structure; under stress, the embedded structure can loose, and a movable dish bottom side wall and a first dish bottom sidewall can move relatively. In addition, by means of a second dish bottom side wall, the phenomenon that a culture medium overflows from the dish bottom can be prevented; by means of a pad table, the phenomenon that an agar culture medium contaminates the dish cover side wall can be prevented; when multiple culture dishes are stacked, a first protrusion and a second protrusion can limit relative movement of the two adjacent culture dishes; by means of a platen, better convenience can be brought to movable dish bottom side wall movement.

Description

technical field [0001] The invention relates to a kind of experimental equipment, in particular to a pressure-out type leak-proof, heightened, non-slip and easy-to-press surface sampling culture dish. Background technique [0002] Petri dish is one of the most widely used experimental equipment in biology. It is often used for the culture test of microorganisms on the surface of food packaging materials, tableware, etc., and the sampling of microorganisms on the surface of the object is usually wiped with a sterile cotton swab on the surface of the object to be tested, or Use sterile filter paper to stick to the surface of the object to be tested, and then transfer the cotton swab or filter paper to the buffer solution for eluting to achieve the purpose of sampling. However, cotton swabs or filter paper cannot completely release the collected microorganisms, which may easily cause incomplete cultivation of cultivable microorganisms; in addition, the sampling of microorganism...

AI Technical Summary

Problems solved by technology

However, cotton swabs or filter paper cannot completely release the collected microorganisms, which may easily cause incomplete cultivation of cultivable microorganisms; in addition, the sampling of microorganisms on the surface of objects requires aseptic operation, while cotton swabs or filter paper are used in the collection and elution of microorganisms. During the process, it is easy to be polluted by environmental microorganisms, and it is difficult to meet the requirements of aseptic operation; these shortcomings will cause the deviation of the microbial test results on the surface of the object

In addition, the operation process of the above method is cumbersome and inefficient, which easily causes waste of human resources
