Petri dishes are an essential tool in microbiology for the cultivation of microorganisms. When selecting and using petri dishes, there are several factors to consider to ensure the success of your experiments. In this blog, we will discuss the important considerations in selecting and using petri dishes. Selecting Petri Dishes The type of petri dish you select will depend on the specific requirements of your experiment. Here are some factors to consider when selecting petri dishes: Material: Petri dishes are commonly made of either glass or plastic. Glass dishes are more durable and can withstand higher temperatures, but they are more expensive and can break easily. Plastic dishes are less expensive and unbreakable, but they are not as heat-resistant as glass dishes. Size: Petri dishes come in various sizes, typically ranging from 50 mm to 150 mm in diameter. The size of the dish you select will depend on the size of the culture you are growing and the space available in your incubator. Sterility: It is essential to choose petri dishes that are sterile to prevent contamination of your culture. Many suppliers offer pre-sterilized petri dishes, or you can sterilize them yourself using an autoclave or other sterilization methods. Using Petri Dishes Once you have selected the appropriate petri dishes, it is essential to use them correctly to ensure the success of your experiment. Here are some tips for using petri dishes: Labeling: Before use, label each petri dish with the relevant information, such as the date, type of media, and type of microorganism. Sterilization: If you are not using pre-sterilized dishes, it is essential to sterilize them before use. This can be done using an autoclave, dry heat, or other sterilization methods. Pouring Media: Prepare the culture medium according to the specific requirements of your experiment and pour it into the sterile petri dish. Allow the medium to solidify before use. Inoculation: Inoculate the culture with the microorganism of interest using a sterile loop or swab. Spread the microorganism evenly across the surface of the medium. Incubation: After inoculation, replace the lid on the petri dish and incubate it at the appropriate temperature and conditions for the microorganism being cultured. Handling: When handling petri dishes, it is important to be gentle to prevent damage to the culture. Avoid touching the surface of the medium or the underside of the lid. In conclusion, selecting and using petri dishes correctly is crucial for the success of your experiments in microbiology. Consider the material, size, and sterility of the dishes when selecting them, and follow proper procedures for sterilization, pouring media, inoculation, incubation, and handling. With these tips in mind, you can use petri dishes effectively to cultivate microorganisms and conduct a wide range of experiments.

A culture dish is a laboratory vessel used for microbial or cell culture. It consists of a disk-shaped bottom and a cover, and is basically made of glass or plastic. Glass is mainly used for plant materials, microbial culture and adherent culture of animal cells. Most of the plastics are made of polyethylene materials, which are disposable and reusable. They are suitable for the operation of inoculation, scribing and bacteria separation in the laboratory, and can be used for the cultivation of plant materials. In 1887, a German scientist named Julius Richard Petri developed a shallow nested disk for laboratory experiments. Before the invention of petri dishes, scientists used test tubes, empty wine bottles and other types of glass jars to culture culture. Unlike these glass containers, the lid of the petri dish is firmly covered on the petri dish, which can well protect the internal culture. In view of the multifunctional characteristics of petri dishes, they are one of the most common equipment in the laboratory. It not only provides an excellent environment for the growth of bacteria, yeast, mold and virus, but also has other uses. They can also be used to observe the behavior of insects, observe the germination of seeds, store samples and evaporate solvents. Petri dish is one of the most important discoveries in the 20th century, and the most well-known one is the discovery of penicillin. Alexander Fleming, professor of bacteriology at St Mary's Hospital in London, was widely praised for the discovery of penicillin in 1928. Noke mainly provides sterilized petri dish that are relatively common in the market, including 6cm, 9cm (2/3/4 rooms) and other specifications. Because the reproduction, growth and development of microorganisms are directly related to the culture medium (nutrition) provided, especially the quantitative analysis, it is of decisive significance to the amount of nutrients provided. Therefore, from the comprehensive consideration of the provision of nutrients, the countable area of colonies, the convenience of operation, and the cost of use, At present, 9cm petri dishes are the most widely used. The bacterial culture dishes are all produced in a 100000 level purification workshop and have been inspected for many times. They are clean and safe, EO sterilized, and free of DNase, RNA enzyme and heat source. The thickness shall be uniform, the surface shall be flat, and free of stains, pits, bubbles, pits, scratches and other defects. The transparency of highly transparent polystyrene should ensure that the substances in the container can be clearly observed and the material is stable. The vent design of the petri dish cover is conducive to gas exchange, and the survival rate of bacteria is high. The convex part minimizes the edge effect. The stacking ring makes stacking and handling easier.
