Cracking-out-type quantitative anti-leakage anti-slip surface sampling culture vessel easy to press

Abstract

The invention discloses a cracking-out-type quantitative anti-leakage anti-slip surface sampling culture vessel easy to press. The culture vessel comprises a vessel bottom and a vessel lid. Under stress, transverse crack openings and longitudinal crack openings formed in first vessel bottom side walls can crack, then movable vessel bottom side walls are detached, then the first vessel bottom sidewalls are lower than the plane of a solid culture medium, and thus the operation of surface microorganism sampling is more convenient. Besides, second vessel bottom side walls can prevent the culturemedium from spilling out from the vessel bottom; when multiple culture vessels are stacked, first protrusions and second protrusions can limit the relative movement of every two adjacent culture vessels; scale lines can indicate the pouring volume of the agar culture medium; press platforms can make the movement of the movable vessel bottom side walls more convenient.

Description

technical field [0001] The invention relates to an experimental equipment, in particular to a split-out leak-proof quantitative non-slip and easy-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 microorganisms on the surface o...

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 culture dish is poured into the agar medium, the pouring volume of the medium is usually determined by the operator according to experience, so the pouring volume of the agar medium of different personnel may have a large difference, thereby affecting the relevant experimental results
