In order to experiment, scientists need access to an extraordinary material with the remarkable ability to capture and hold even a single-celled organism like bacteria or other micro-organisms. They use special plates for that called Petri dishes. The basic structure of a round and flat petri dishes. They come in plastic or glass and have snap-on/flip lids. We will use this text to understand the various Petri dishes and how they are applied and its purpose in science. Kangwei Medical is here to help you.
The Suitable Petri Dish for Your Experiment
The different shapes of the Petri dishes are selected by the scientists for experiments. People consider a lot of things when they are about to choose the perfect dish as per their requirements. It includes many aspects like
Size
Material (plastic or glass)
Shape (round or square)
Depth
If it has a grid or lines across the bottom to help count cells
This is key as the size of the Petri Dish decides how much bacteria will grow in it. If you want even more bacteria, youll need a larger plate so be sure to provide enough room for them. What the dish is made of matters for at least for one reason: some kinds of bacteria will do better on glass vs. plastic based on the materials that are on the dish itself Even the dish shape can influence how the bacteria grow and move around in an agar plate.
How They Affect Your Results
Which Petri dish are you usingCan a choice of the correct Petri dish and plastic test Tube really influence your results that much! For instance, if you use a small dish, the bacteria may not grow well. If the dish is too shallows, the bacteria will dry out and so your experiment is screwed. Moreover, if the dish has a grid on its bottom and you mistakenly count those cell cells then your outcomes may also be invalid. This could result in misinterpretations of what you were attempting to study.
PETRI DISH PREPARATION The Sterilization Step
This step is super important because if there are extra bacteria hanging around on the dish they could skew the experiment leading to an incorrect result. Accurate data depends on a clean dish.
Creative Designs of Petri Dish and Its Applications
The improvement carried out by scientists for Petri dishes is limitless. The new designs were built with barriers to prevent contamination, meaning its near impossible for any undesirable bacteria to get it. These are re-usable plates which is very eco-friendly. There are plastic dishes that are transparent and can be viewed under a microscope while they are in the dish so you do not have to open them.
Versatility of Petri Dishes: A Hunt in Life-Science
They are the undisputed workhorses of scientific research, these petri dishes and urine cup. These are used in a variety of fields, all the way down to studying tiny microscopic organisms like bacteria and even genetics and chemistry. Using the right Petri dish and growing conditions, many kinds of bacteria, viruses or other microorganisms can be cultured and researched by scientists.
