1, clean the workbench
Microorganisms are sterile culture in a specific culture medium, so sterile culture needs a clean workbench to provide a sterile working environment.
Step 2 Incubator
There are many types of incubators whose function is to provide a suitable environment for the growth of microorganisms. The biochemical incubator can only control the temperature, and can be used as a plate culture for general bacteria. The mold incubator can control the temperature and humidity and can be used for mold culture; The CO2 incubator is suitable for the cultivation of anaerobic microorganisms.
Step 3 keep balance
Balance is used to accurately weigh various reagents. Electronic balance is commonly used in laboratories, and there are different grades of electronic balance according to different accuracy.
4. Microbial homogenizer
Used to extract bacteria from solid samples. Microbial detection samples prepared by microbial homogenizer have the characteristics of no pollution, no damage, no temperature rise, no sterilization treatment, no washing utensils and so on. It is a convenient microbial experimental instrument. ?
5, colony counter
The colony counter can help the operator count the number of colonies. By magnifying, photographing and counting, the number of colonies can be accurately obtained. Some high-performance colony counters can also be connected to the computer to complete the automatic counting operation. ?
6. Microwave/electric stove
Used for rapid heating of solution and heating and melting of microbial solid culture medium.
7. Autoclave
Most experimental articles, reagents and culture media used in microbiology should be strictly sterilized. Sterilization pots also come in different sizes and models, some are manual and some are fully automatic. Users need to buy according to their own needs. ?
8. straws?
Liquid level gauge is used to accurately measure various liquids. Common liquid measuring tools include measuring cylinder, pipette, micro-liquid extractor, graduated test tube and beaker.
9. Low temperature refrigerator
Refrigerator is an indispensable instrument for storing reagents and samples in the laboratory. Some reagents used in microbiology experiments are required to be stored at 4 degrees, while others are required to be stored at MINUS 20 degrees. The experimenter must see clearly the storage conditions of the reagent and store it at a suitable temperature.
10, biosafety cabinet
Some reagents and sample microorganisms involved in microbial experiments are toxic and harmful to operators. In order to prevent the spread of harmful suspended particles and aerosols, biosafety cabinets can be used to provide safety protection for operators, samples and cross-infection between samples and the environment.
