Split-out anti-leakage anti-skid visible sector counting surface sampling culture dish

Abstract

The invention discloses a split-out anti-leakage anti-skid visible sector counting surface sampling culture dish. The culture dish comprises a dish bottom and a dish cover, a horizontal cracking gap and a longitudinal cracking gap which are formed in a first dish bottom side wall can be split under stress to allow a movable bottom side wall to be released causing the height of the first dish bottom side wall to be lower than the plane of a solid substrate, so that the sampling operation of surface microorganisms is more convenient, in addition, a second dish bottom side wall can prevent culture mediums from leaking from the dish bottom, when multiple culturing dishes are stacked, first and second protrusions can limit the relative moving of the two adjacent culture dishes, the observationof micro colonies can be more convenient by arranging an observation window, and the counting process of colonies can be simplified by radioactive rays.

Description

technical field [0001] The invention relates to an experimental equipment, in particular to a split-out leak-proof and anti-skid visible fan-shaped counting 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 surf...

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 colony of the target culture grown on the medium in the petri dish is small, it is necessary to enlarge the colony with a microscope to observe the accurate shape of the colony, and the petri dish needs to be opened during the magnification and observation of the colony, which may cause pollution or spillage of harmful cultures

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
