Abstract

The invention discloses a split type quantitative and visible easy-to-mark surface sampling petri dish. The petri dish comprises a dish bottom and a dish cover. When being stressed, at least one transverse crack opening and at least one longitudinal crack opening formed in at least one first dish bottom side wall can be split, a movable dish bottom side wall is separated, and the at least one first dish bottom side wall is lower than the plane of a solid medium, so that surface microorganism sampling operation is simpler and more convenient; marking work can be more efficient by a marking region, observation of minute colonies can be more convenient by an observation window, and scale lines can indicate the pouring volume of an agar medium.

Description

technical field

[0001] The invention relates to an experimental equipment, in particular to a split-type quantitative and easy-to-mark visible 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 r...
