A Petri dish is a tool that is often used in a lab. A petri dish, also called a Petri dish, is a round container made of clear glass or plastic. It is usually used to grow cells or microorganisms.
In 1877, a German bacteriologist named Julius Richard Petri was said to have been the first person to use a Petri dish. When he was growing microorganisms, he felt like things were coming apart.
Before Petri dishes were invented, people who studied microorganisms used shallow bowls or bottles to grow more of them. But these containers quickly get dirty, making it hard to do research.
Normal Petri dishes come in pairs, with a small dish for the container and a large cup for the lid. The lid is important because it keeps other things from getting into the petri dish where microorganisms are grown.
If you are starting, there is a lot you should know about Petri dishes. And to find out more, let’s look at what the following Petri dishes are for and how to use them right!
Petri Dish Functions
Petri dishes play a very important role in biology and chemistry labs and serve a very important purpose for research. In each lab, the petri dish is used for a different thing.
- The first thing a petri dish does is act as a place for cells or microorganisms to grow. It gives them a lot of room to grow and keeps them from getting contaminated by other organisms.
- Because they are made of clear glass, it is easy for scientists to see how microorganisms grow in Petri dishes.
- It can be used as a place to put media for growing cells. Most of the time, gel or agar is used to grow cells in Petri dishes.
- It can be used as a container to look at with a microscope without moving the thing to look at to a glass slide.
- Petri dishes store chemicals in chemistry labs because you can use a lid, aluminum foil, or a watch glass to close the petri dish.
- Under certain conditions, the petri dish can be used as a place for chemicals to dry or evaporate. This is because the petri dish has a large surface area, which speeds up the process of evaporation or drying.
How to Use a Petri Dish
Here’s how to use the correct and proper petri dish according to the usage procedure:
- Before you use a petri dish, make sure it is clean, sterile, and free of germs, dirt, fungus, and other things that could be harmful. This is to keep things from getting dirty.
- Put the medium for growing cultures into the petri dish. If you want to grow bacteria, ensure the medium you use has nutrients, indicators, salts, and antibiotics that help microorganisms grow and develop.
- After putting the media in the petri dish, the next step is to put the cup in the fridge so that it doesn’t come into contact with anything else.
- The sample from the microorganism is then entered. This sample will later be looked at, so it’s important to be careful when taking it. Slowly move the sample and don’t push too hard. This is to keep the cultural media from getting broken or damaged.
- If the sample of microorganisms was moved successfully, put a lid on the petri dish and keep it at 37 degrees Celsius. Keep the sample in the Petri dish for a few days so that the microorganisms you want to study can grow.
- If the sample in the petri dish has grown, it can be used for research.
So this describes what a petri dish is and how to use it. It is very important to know how to use Petri dishes in the lab so that research can be done well. We hope that the above information can help.
