Extrusion-type leakproof antiskid hand-held fan-shaped counting surface sampling culture dish

Abstract

The invention discloses an extrusion-type leakproof antiskid hand-held fan-shaped counting surface sampling culture dish. The extrusion-type leakproof antiskid hand-held fan-shaped counting surface sampling culture dish comprises a dish bottom and a dish cover; the dish bottom is provided with a second buckle and a first buckle; a stable inosculating structure is formed by the second buckle and the first buckle; when the stable inosculating structure is loaded with force, the second buckle and the first buckle are disconnected, relative movement of a movable dish bottom side wall with a firstdish bottom side wall is realized; a second dish bottom side wall is capable of preventing leakage of culture medium from the dish bottom; the cooperation of a first clamping edge and a second clamping edge is capable of realizing convenient disconnecting and connecting of the dish bottom and the dish cover; when a plurality of the extrusion-type leakproof antiskid hand-held fan-shaped counting surface sampling culture dishes are stacked, first convex parts and second convex parts are capable of limiting relative movement of two adjacent extrusion-type leakproof antiskid hand-held fan-shaped counting surface sampling culture dishes, and radiative lines are adopted to simplify bacterium colony counting process.

Description

technical field [0001] The invention relates to an experimental equipment, in particular to a pressure-out leak-proof and anti-skid hand-held fan-shaped counting 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 microorganisms on the...

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

When the number of colonies of the target culture grown in the culture medium in the petri dish is huge, the counting process of the colonies is more cumbersome
