Biological culture dish

Abstract

The invention belongs to the technical field of design of biology laboratory equipment, and in particular discloses a biological culture dish, comprising a round culture dish, wherein an azimuth marker is arranged on the upper wall of the culture dish; a circular ring-shaped connecting disk is arranged in the center of circle of the culture dish, a plurality of grooves are arranged uniformly inward on the circumference of the connecting disk, and an annular truncated cone with the same center of circle is arranged above the center of the connecting disk; the grooves are matched with a clamping piece arranged on one end side of a division plate to clamp the division plate onto the connecting disk; the division plate is strip-shaped and is composed of solid slats at the upper part and comb teeth uniformly and transversely arranged at the lower part of the slats, and through slots are formed between adjacent comb teeth; the clamping piece is arranged at the connection part between the slats and comb teeth; and the culture dish, connecting disk and division plate are all separately designed. The biological culture dish is mainly suitable for culturing microbes or animal and vegetable tissues and other bacteria in biology laboratory.

Description

technical field [0001] The invention belongs to the technical field of design of biological laboratory equipment, and specifically discloses a biological petri dish, which is mainly suitable for cultivating microorganisms such as bacteria or animal and plant tissues in a microbiological laboratory. Background technique [0002] At present, the circular plates (petri dishes) widely used in microbiology laboratories or animal and plant tissue culture operations have the following disadvantages: the petri dishes cannot be partitioned, and it is very inconvenient to do comparative experiments on bacteria, animal and plant tissues; because they are round In many cases, the operator will draw or mark with a marker pen on the back of the petri dish, so that if it is wiped off, the experiment can only be redone; in the process of animal and plant tissue culture, only on the lid of the dish Drawing area division lines and lacking strict physical separation not only makes it difficult...

[0002] At present, the circular plates (petri dishes) widely used in microbiology laboratories or animal and plant tissue culture operations have the following disadvantages: the petri dishes cannot be partitioned, and it is very inconvenient to do comparative experiments on bacteria, animal and plant tissues; because they are round In many cases, the operator will draw or mark with a marker pen on the back of the petri dish, so that if it is wiped off, the experiment can only be redone; in the process of animal and plant tissue culture, only on the lid of the dish Drawing area division lines and lacking strict physical separation not only makes it difficult to distinguish between different treatment groups in the experimental operation, but also leads to doubts about the reliability of the test results; when pouring the culture medium into the petri dish, the thickness of the culture medium cannot be guaranteed In most cases, the operator will shake the petri dish back and forth until the culture medium seems to have the same thickness around it. These details will introduce errors and seriously affect the accuracy of the experimental results.
