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
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

Embodiment Construction
[0009] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the described embodiments are only used to explain the present invention, and all simplifications or equivalent changes based on the technical solutions of the present invention fall within the protection scope of the present invention.
[0010] In the discussion of specific embodiments, the shape of the split-type quantitative hand-held fan-shaped counting surface sampling petri dish is preferably selected as a circle, but those familiar with the art should recognize that the present invention is also applicable to such as oval , rectangle, or other suitable shape for Petri dishes.
[0011] The invention discloses a split-out quantitative hand-held fan-shaped counting surface sampling petri dish, which comprises...

The invention discloses a cracking-type quantitative handheld fan-shaped counting surface sampling culture dish. The culture dish comprises a dish bottom and a dish cover, wherein when the culture dish is under stress, transverse crack openings and longitudinal crack openings formed in first dish bottom side walls can be cracked, so that movable dish bottom side walls are separated, resulting in that a height of the first dish bottom side walls is lower than a plane of a solid culture medium, and the surface microorganism sampling operation is simpler and more convenient; by virtue of the cooperation of first tongs and second tongs, the dish bottom and the dish cover can be more convenient to open or lock; by arranging scale lines, a pouring volume of an agar culture medium can be indicated; and by arranging radioactive rays, the counting process of the colony can be simplified.
Description
technical field [0001] The invention relates to an experimental equipment, in particular to a split-out quantitative hand-held fan-shaped counting 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 objec...
