Pressing-out-type quantitative, leakproof and skid-resistance surface sampling culture dish easy to mark

Abstract

The invention discloses a pressing-out-type quantitative, leakproof and skid-resistance surface sampling culture dish easy to mark. The culture dish comprises a dish bottom and a dish cover, the dishbottom is provided with second buckles and first buckles, the second buckles and the first buckles are of a stable embedding structure, and the embedding structure can be loosened when the culture dish is under stress, so that movable dish bottom side wall bodies and first dish bottom side walls move relatively. Besides, second dish bottom side walls can prevent a culture medium from spilling outof the dish bottom, and when multiple culture dishes are stacked, first protrusions and second protrusions can limit the relative movement of every two adjacent culture dishes, a marking area can makemarking work more efficient, and scale marks can indicate the pouring volume of the agar culture medium.

Description

technical field [0001] The invention relates to an experimental equipment, in particular to a pressure-out leak-proof quantitative easy-to-mark non-slip 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 ...

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

Most of the existing petri dishes are made of glass and need to be marked with an oil-based marker pen. However, the handwriting of the oil-based marker pen needs to be erased with a special organic solvent. Therefore, when multiple petri dishes are used repeatedly, the inconvenience of marking will easily cause to confuse

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
