Abstract

The invention discloses a press-out-type non-slip easy-press hand-held fan-shaped counting surface sampling culture dish which comprises a dish bottom and a dish cover. The dish bottom is provided with a second clasp and a first clasp which are in a stable chimeric structure. The chimeric structure can be loosened when a force is applied, so that a movable dish bottom side wall moves relative to afirst dish bottom side wall. Through cooperation of a first grasping handle and a second grasping handle, the dish bottom and the dish cover can be more convenient to open or close. When multiple culture dishes are stacked and placed, a first bulge and a second bulge can limit the relative movement of two adjacent culture dishes, a pressing platform can make the movement of the movable dish bottom side wall more convenient, and radioactive lines can simplify the counting process of bacterial colonies.

Description

technical field

[0001] The invention relates to an experimental equipment, in particular to a push-out type non-slip and easy-to-press hand-held 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 ...
