Liquid nitrogen machine is a basic laboratory instrument

　　A microbiology laboratory is a necessary facility in the biological field. Currently, an increasing number of industries, including environmental testing, traditional Chinese medicine extract testing, and Western medicine preparations, have explicit requirements for microbiological testing.

　　Therefore, we need to configureLaboratory liquid nitrogen machineto conduct a complete microbiology laboratory? Let's take a brief inventory.

　　Laboratory liquid nitrogen machineClean bench: Sterile culturing of microorganisms in specific culture media requires a sterile work environment provided by a clean bench.

　　Incubator: There are many types of incubators; their function is to provide a suitable environment for microbial growth. Biochemical incubators only control temperature and can be used for the general cultivation of bacteria; fungal incubators can control both temperature and humidity and can be used for the cultivation of fungi; CO2 incubators are suitable for the cultivation of anaerobic microorganisms.

　　Balance: Used for weighing various reagents. Electronic balances are commonly used in laboratories; electronic balances have different grades according to their different precisions.

　　Microorganism homogenizer: Used to extract bacteria from solid samples. In microbiological experiments, using a microbial homogenizer to prepare microbial test samples is a more convenient instrument, featuring sample homogenization, non-destructive nature, no temperature change, no sterilization needed, and no need to wash containers.

　　Colony counter: Helps operators count the number of colonies. Accurately obtains the number of colonies through magnification, photography, counting, and other methods. Some high-performance colony counters can also be connected to a computer to complete automated digital operations.

　　Laboratory liquid nitrogen machineHeating plate: Used for rapid heating of solutions and dissolving solid microbial culture media.

　　Autoclave: Used for sterilization. Most experimental items, reagents, and culture media for microorganisms require strict disinfection and sterilization. Autoclaves come in various sizes and models, some manual and some fully automatic. Users should purchase according to their needs.

　　Pipette: A liquid quantifier for measuring various liquids. Commonly used liquid quantifiers include graduated cylinders, pipettes, micropipettes, graduated test tubes, and beakers.

　　Centrifuge: Used to collect microbial cells and other precipitates. Centrifuges can be divided into refrigerated and room temperature types. Depending on the type of sample, some samples require

　　Laboratory liquid nitrogen machineLiquid nitrogen tank: Stores liquid nitrogen and can be used for long-term storage of various microorganisms such as bacteria, yeasts, molds, and macrofungi.

　　The above are the basic instrument configurations for a microbiology laboratory. When establishing a laboratory, some other consumables are also needed, such as alcohol lamps, test tube racks, Erlenmeyer flasks, measuring tubes, glass test tubes, sterile pipettes, drying racks, scissors, tweezers, absorbent cotton, gauze, test tube baskets, sterile sampling and weighing bags, inoculating loops, filters, laboratory liquid nitrogen machines, etc. Experimenters can equip the microbiology laboratory with suitable instruments and consumables based on the needs of different industries.
