Cell culture dish for biological lessons

Abstract

The invention relates to the technical field of medical culture dishes, and discloses a cell culture dish for biological lessons, which comprises a culture dish body, a glass partition plate is movably connected to the interior of the culture dish body, a cover plate is clamped to the upper end of the culture dish body, a plug body is movably connected to the interior of the cover plate, and a shell is movably connected to the lower end of sponge. A heating pipe is movably connected to the interior of the shell, a triggering device is fixedly connected to the interior of the shell, a metal ball is fixedly connected to the interior of the shell, a triggering block is fixedly connected to the interior of each supporting leg, an electromagnet is fixedly connected to the upper end of the shell, and an electrorheological fluid is fixedly connected to the interior of each fixing piece. A permanent magnet is fixedly connected to the outer part of the push rod. The cell culture dish for biological lessons has the advantages that when the culture dish is moved, the culture dish can be stably fixed and prevented from falling off. Meanwhile, three same cavities are formed in the device, a group of control experiments can be conducted at the same time, and the accuracy of experimental results is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical culture dishes, in particular to a cell culture dish for biology classes. Background technique [0002] A petri dish is a laboratory vessel used for microorganism or cell culture. It consists of a flat disc-shaped bottom and a cover plate. It is usually made of glass or plastic. Nowadays, with the development of education in our country Progress, the laboratory has entered junior high school or even elementary school to cultivate students' scientific literacy, but when students take out or place the petri dish, due to the naughty children, they often can't hold it stably, causing the petri dish to fall to the ground and cause it to break. Danger occurs, and at the same time, when it is necessary to do a controlled experiment, it is often necessary to take several petri dishes for separate experiments, resulting in poor control of independent variables and difficulty in obtaining accurate experimen...
