Since the outbreak of the novel coronavirus pneumonia in 2020, the use of medical equipment such as syringes, petri dishes, and pipette tips has also risen sharply. If you are a manufacturer that provides petri dishes to medical institutions, the best way is to buy injection molding machine for petri dish, which can greatly improve the efficiency of your production line.

Benefits of injection molding machine for medical treatment

Injection molding machines play an important role in the production of petri dishes and other medical plastic products. It undertakes most of the production links of medical devices, and medical device manufacturers ensure the lowest production risks.

The cost of the injection molding machine accounts for less than 5% of the investment in the entire medical injection molding production line. However, this 5% investment ratio can ensure the safe production of medical devices and reduce unnecessary pollution risks.

Why is a petri dish used?

A petri dish is suitable for anti-epidemic stations, hospitals, biological products, food industry, pharmaceutical industry and other units, used for bacterial isolation and culture, antibiotic potency inspection and qualitative inspection analysis. In agriculture, aquaculture and other scientific researches, it is used for artificial cultivation and incubation of seeds, plants, insects, and fish species. Used as a utensil in the electronics industry or other industries.

What you need to know when using petri dish

1. Clean and disinfect before use. If the petri dish is not clean, it will has a great impact on the work, which can affect the pH of the culture medium. Plus, if certain chemicals are on here, it will inhibit the growth of bacteria.

2. The newly purchased petri dish should be rinsed with hot water first, and then soaked in a hydrochloric acid solution with a mass fraction of 1% or 2% for several hours to remove free alkaline substances, and then rinsed with distilled water twice.

3. If you want to culture bacteria, then use high-pressure steam (usually 6.8*10 to the 5th power of Pa high-pressure steam), sterilize at a temperature of 120 ℃ for 30 minutes, dry at room temperature, or sterilize with dry heat, that is, the petri dish Put it in an oven and keep the temperature at about 120℃ for 2 hours to kill the dentition of bacteria.

4. Only sterilized petri dishes can be used for inoculation and culture.

5. Why turn the petri dish upside down during lithographic culture:

During cultivation, a large amount of water vapor will be generated in the petri dish, and the water vapor will condense on the lid of the dish to produce water droplets. If the petri dish is placed upright, the dripping of the water droplets will wash away the colonies. In this case, a large colony may be scattered into many small colonies. Colonies cause great trouble to the cultivation and counting of bacteria. If it does, the culture medium is on top, and the dish cover is on the bottom, and the water droplets will not drip onto the colony.

Finally

Use our affordable injection molding machine for petri dish to achieve the same safe, high-precision and high-efficiency production. Moreover, the parts of the machine are easy to remove dust and the injection molding machine is kept clean, so that the production of medical equipment can be carried out stably, reducing the cost of equipment replacement for production enterprises.
