Microbial medium preparation device, microbial medium preparation method and packaging method

Abstract

The invention belongs to the technical field of microbial research and development, and discloses a microbial culture medium preparation device, which includes a preparation tank, a culture medium bag and a controller box. The water inlet pipe and the water outlet pipe, the water inlet pipe of the culture medium bag is connected to the water source, the 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, and there is a The heating unit and the control unit, the heating unit heats the preparation tank, a temperature sensor is arranged in the preparation tank, the temperature sensor is connected to the control unit, and the control unit adjusts the temperature of the culture medium solution in the preparation tank in real time according to the feedback from the temperature sensor. Set up the mixer. Through the newly designed preparation device and preparation method of the present invention, the preparation of the culture medium achieves lower nutrient substance destruction, less manual intervention and rapid realization of the preparation of a larger volume of 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 packaging 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 be...

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 easy 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 medium preparation device sold on the market is more than two to three hundred thousand yuan. Many microbiology laboratories cannot use it due to limited funds.
