This is to stop condensation from forming on the top of the lid. Condensation causes two problems (1) It will allow contamination to enter into the dish by moving accross the water film from the outside (2) It can create a tight seal and prevent oxygen entering the petri dish making it go anerobic.
What else can I help you with?
Why are petri plates inverted for incubation?
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 glass container used to prepare cultures in science lab?
beakercould be a petri dish
How do you use an petri dish?
a petri dish is used to study small things
What is Julius Richard Petri known for?
Julius Richard Petri is known for being the inventor of the petri dish. In early bacteria studies, cultures were kept in lidless dishes and as a result they often became contaminated. Julius Richard Petri invented a dish with a lid that reduced the risk of contamination and this has become known as the petri dish.
Tools scientist use?
The list is so exhaustive that I'm not even going to try, but I'll tell you about the tools/equipment I use. I study geophysics, and often have to collect data to try and understand the structure of the Earth. I use magnometers to measure the magnetic field strength, gravimeters to measure the gravitational field strength, terrameters (and occasionally something called an EM34) to measure the resistivity of the immediate subsurface, and a seismometer with an array of geophones to detect irregularities (such as geological changes) using seismic waves.
Why are inverted plates during incubation?
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.

Why are the inoculated petri dishes incubated overnight?
Inoculated petri dishes are incubated overnight to allow the bacteria or other microorganisms to grow and form colonies. This extended incubation period provides enough time for the organisms to multiply and become visible, making it easier to analyze and identify them.
Importance of flaming the edges of the petri plates before and after pouring the media?
Flaming the edges of the petri plates before pouring the media helps to create a sterile environment by killing any microorganisms present on the surface. Flaming the edges after pouring the media helps to prevent contamination of the agar surface by airborne microorganisms during incubation.
Do you put petri dishes in the autoclave?
Yes, petri dishes can be autoclaved to sterilize them. It is important to ensure that the petri dishes are made of materials that are autoclavable and that they are placed in appropriate autoclave-compatible containers before sterilization to prevent breakage.
Why we put the inverted petridish in the incubater after streaking?
Placing the inverted Petri dish in the incubator after streaking helps prevent contamination from condensation dripping onto the streaked agar surface. It also helps to maintain a sterile environment by protecting the surface of the agar from airborne contaminants that may settle on it during incubation.
Why petri dish need to be wrapped during sterilization?
They may be contaminated MORON.
Why petri dish is inverted in incubation in membrane filtration method?
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.
Why should you label the petri dishes correctly?
The importance of labeling petri dishes is important. When looking at reaction on specimens or the growth of bacteria of items in a petri dish, if it is labeled incorrectly the data will be wrong and projects could be jeopardized.
What is the birth name of Petri Sarvamaa?
Petri Sarvamaa's birth name is Petri Ilari Sarvamaa.
What is the birth name of Miguel Petri?
Miguel Petri's birth name is Miguel Angel Petri.
