Press-type anti-sliding easy-press sector counting surface sampling culture vessel

Abstract

The invention discloses a press-type anti-sliding easy-press sector counting surface sampling culture vessel. The culture vessel comprises a vessel bottom and a vessel cover. A second clamping buckleand a first clamping buckle which are of a stable embedding structure are arranged at the vessel bottom. When bearing force, the embedding structure can be loosened, so that a movable vessel bottom side wall moves relative to a first vessel bottom side wall, when multiple culture vessels are placed in a stacked mode, relative moving of every two adjacent culture vessels can be limited through a first protrusion and a second protrusion, a movable vessel bottom side wall can move more conveniently through a pressing table, and the bacterial colony counting process can be simplified through radioactive rays.

Description

technical field [0001] The invention relates to an experimental equipment, in particular to an extrusion-type non-slip and easy-press 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 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 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
