The invention relates to the technical field of biological experiment equipment, and discloses an automatic culture solution injection device for a biological culture dish. The automatic culture solution injection device comprises a culture dish body and a culture dish cover; an accommodating cavity is formed inside the culture dish body; the inner wall of the accommodating cavity is fixedly connected with a traction spring; the bottom of the traction spring is fixedly connected with an inner culture cavity; and the bottom of the inner culture cavity is fixedly connected with a first dielectric medium plate. According to the automatic culture solution injection device for the biological culture dish, along with growth and development of a biological object in the inner culture cavity, theinner culture cavity gradually moves upwards under the drive of the traction spring, when culture solution is reduced to a certain degree, a first positive plate and a first negative plate are connected, a one-way liquid outlet valve is opened at the moment, an electromagnet is powered on and has magnetism so as to extrude the culture solution in an elastic solution storage cavity from an extrusion nozzle until the feeding is completed, the inner culture cavity is sunk again, and the solution feeding is stopped; the automation degree is high, the quantitative solution feeding is implemented, the manual operation does not need to be carried out, and the nutritional requirements in the culture dish are ensured.
Description
technical field [0001] The invention relates to the technical field of biological experiment equipment, in particular to a culture solution automatic injection device for biological culture dishes. 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. It is generally made of glass or plastic. It is suitable for laboratory inoculation, streaking, and separation of bacteria. It can be used for the cultivation of plant materials. When the biological petri dish is used, it is usually necessary to inject culture fluid into the petri dish as a nutrient base for the growth of biological materials or bacteria. [0003] The culture medium is an artificially prepared nutrient for the growth and maintenance of microorganisms, plants and animal tissues, and generally contains carbohydrates, nitrogenous substances, inorganic salts (including trace elements), vitamins and water, etc.,...
