A Petri plate is inverted to prevent contamination from airborne particles and moisture that can accumulate on the lid. This positioning allows condensation that may form on the lid to drip back into the agar rather than onto the culture, which could disrupt microbial growth. Inverted plates also facilitate better observation of colonies without interference from the lid.
Petri Sarvamaa's birth name is Petri Ilari Sarvamaa.
Petri Walli died in 1995.
Ad Petri Cathedram was created in 1959.
Petri Kotwica was born in 1964, in Parainen, Finland.
Yes he is. Her name is Tina and she has a Petri Lindroos profile on myspace.
to prevent condenstion of the gel
This inversion prevents moisture condensing on the surface of the plate. That would make a problem in that the growth on the plate would be "distorted" by the water making ID more difficult.
Because during incubation moisture will form at the top of the petri dish. Inverting the dish prevents it from dropping into whatever you have in the petri dish.

it is to prevent the moisture formed due to condensation of the agar ,to mix with the components present in the petri plates, else causes contamination
A shallow plate which is used in a science lab is known as a petri dish.
Carefully.
An agar plate is a specific type of Petri dish that contains a solid growth medium called agar. Petri dish is a broader term that refers to any shallow, flat, circular dish used in microbiology experiments. The key difference is that an agar plate contains agar as a solid medium for microbial growth, while a Petri dish can be used with various types of media, including agar.
The clumps of growth are called colonies.
A petri dish is a shallow, round glass or plastic dish used to hold agar, a gel-like substance that provides nutrients for growing microorganisms. An agar plate is a petri dish containing agar with added nutrients and is used to culture and grow specific microorganisms for study. The main difference is that an agar plate contains nutrients specifically tailored for the growth of certain microorganisms, while a petri dish may not contain any added nutrients.
If media splashes up the side of a petri plate, it can result in contamination from the outside environment or other plates. It may also affect the growth of the culture as the splashed media can mix with the top agar layer. To prevent inaccurate results and contamination, it is best to discard the petri plate.
