Microbial culture medium preparation device and method and subpackaging method

Abstract

The invention belongs to the technical field of microbial research and development, and discloses a microbial culture medium preparation device which comprises a preparation tank, a culture medium bag and a controller case, wherein the preparation tank is provided with a feed pipe and a discharge pipe; the culture medium bag is provided with a water inlet pipe and a water outlet pipe; the water inlet pipe of the culture medium bag is connected with a water source; a water inlet end of the culture medium bag is provided with a water inlet filter; the water outlet pipe of the culture medium bag is connected to the feed pipe of the preparation tank; a heating unit and a control unit are arranged in the controller case; the heating unit is used for heating the preparation tank; a temperature sensor is arranged in the preparation tank and connected to the control unit; the control unit is used for adjusting the temperature of the culture medium solution in the preparation tank in real time according to the feedback of the temperature sensor; and a stirrer is arranged in the preparation tank. By using the newly designed preparation device and preparation method, the culture medium can implement less nutrient destroy and less manual intervention, and can quickly implement preparation of the larger-volume culture medium.

Description

technical field [0001] The invention belongs to the technical field of microbial research and development, in particular to a microbial culture medium preparation device, a microbial culture medium preparation method and a packing method. Background technique [0002] The culture medium is an essential nutrient substance prepared artificially for the growth, reproduction, metabolism and product synthesis of microorganisms. Culture medium is widely used in microbial testing of pharmaceutical and biological products, food, cosmetics, and disposable hygiene products, as well as water quality inspection and clinical testing. In addition, it is also used in the field of research, development and production related to the isolation and cultivation of microorganisms, animal and plant cells. In recent years, with the development of the biotechnology industry, activities such as research and development, production, and inspection and analysis in the above-mentioned fields have beco...

Problems solved by technology

The raw materials packaged in this specification cannot be used up in a short period of time in most microbiology laboratories. A bottle of culture medium raw materials is often used repeatedly, sometimes even across several quarters or years. During this period, due to Opening the package again and again leads to problems such as moisture absorption, agglomeration, deterioration, discoloration, insects, and cross-contamination between different reagents and bottles during weighing of the medium raw materials

Finally, the quality of culture medium prepared in different periods is unstable and fluctuates greatly, which makes the test results inaccurate, the reliability is reduced, and the comparability of scientific research data between different laboratories is poor;

[0013] 4. Dust is likely to be generated during the weighing and transfer of powdered medium raw materials. On the one hand, it will pollute the weighing instrument and the production or scientific research environment that requires high cleanliness. On the other hand, it will be inhaled by the operator, causing allergies or Discomfort, endangering health;

[0014] 5. The equipment is expensive. The price of the automatic culture medium preparer sold on the market is more than 200,000 to 300,000 yuan. Many microbiological laboratories cannot use it due to limited funds.
