What is Petri's food?

Petri's bowl is a type of glass or plastic shallow round round round round round round lid, which is a vital tool in scientific laboratories. Use for Petri's bowl is diverse, but is the best known for holding the culture medium on which cells, bacteria and viruses can be grown and studied. Most of the main scientific breakthroughs were very assisted by using Petri's meals, whether they include a virus structure or the ability to clone meat. Most scientists used shallow bowls or bottles that were unpleasant to work and subject to contamination. Petri thought it would be easier to work with a shallow circular ball and easy to make the lid. The lid prevents the contaminated Petri bowl and the basic shape easier to stack and arrange in various configurations.

When Petri's bowl is used for culture cells, it is usually filled with a growth medium made of agar, a gel made of red algae extracts and a number of nutrients. Growth medium has a gelatin texture on which withThe most cultures are doing well, although sometimes nutrients must be changed to meet the needs of a cultivated organism. To meet the needs of fine organisms, the scientist can take several weeks to adjust the environment of a series of Petri's meals. Once the culture begins to prosper, the body can be explored.

There are other uses for Petri's bowl: for example, many schools are used to teach students about seed germination, because clear food allows the observer to see every step of growth. In addition, Petri's bowl is commonly used for an autopsy because it is ideally located under a microscope. Petri's bowl can also be used for basic experimental purposes, such as transport of fluids in Sterile containers or drying fluids for study.

Further use for Petri's bowl is constantly exploring the scientific community and it is a laboratory tool that is unlikely to be abandoned in the near future. Main progress in science, such as growing cells integrated with electronic circuits, cloning of organs andUnderstanding viruses were achieved using a modest Petri bowl. Although other methods of studying organisms in the laboratory are developing, the need to cultivate organisms quickly in a sterile environment will never disappear.
