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

Abstract

The invention discloses a press-out type leakage-proof cover-raised surface sampling petri dish easy in marking. The petri dish comprises a petri dish bottom and a petri dish cover and is characterized in that the petri dish bottom is provided with second fasteners and first fasteners, the second fasteners and the first fasteners are in a stable fastening structure, and the fastening structure canbe unfastened when being stressed to allow movable petri dish bottom lateral walls to move relative to first petri dish bottom lateral walls; second petri dish lateral walls can prevent a culture medium from overflowing from the petri dish bottom, support platforms can prevent the agar culture medium from polluting petri dish cover lateral walls, and efficient marking can be achieved through marking areas.

Description

technical field [0001] The invention relates to an experimental equipment, in particular to a pressure-out leak-proof, elevated and easy-to-mark surface sampling petri 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 of objects...
