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

Abstract

The invention discloses a press-out type handheld surface sampling petri dish easy in pressing and adopting sector counting. The petri dish comprises a petri dish bottom and a petri dish cover and ischaracterized 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, the fastening structure can be unfastened when being stressed to allow movable petri dish bottom lateral walls to move relative to first petri dish bottom lateral walls, the petri dish bottom and the petri dish cover can be conveniently separated from or fastened to each other through the coordination of first grippers and second grippers, the movement of the movable petri dish bottom lateral walls can be facilitated by pressing protrusions, and the counting process of bacterial colonies can be simplified by radial lines.

Description

technical field [0001] The invention relates to an experimental equipment, in particular to a push-out type easy-to-press 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 ...
