Mandar Consultancy is the best laboratory petri dish supplies in Toronto. A laboratory Petri dish is a shallow, circular dish made of glass or plastic that is commonly utilized in microbiology to civilization and swell microorganisms. The dish is named after its originator, Julius Richard Petri, a German microbiologist.
Petri dishes typically have a diameter of 90mm or 150mm, although smaller or larger sizes are also available. The dish has a lid that fits snugly over the top, which assists to avert contamination of the culture by airborne bacteria or fungi. The lid may also have ventilation holes to allow for the interchange of gases.
To use a Petri dish, a nutrient-rich agar avenue is poured into the dish and allowed to harden. A little amount of a microbial sample is then introduced to the surface of the agar, either by swabbing a surface or by transferring a small-scale amount of moisture containing the microorganisms. The dish is then incubated under appropriate conditions, such as temperature and humidity, to permit the microorganisms to sprout and form colonies on the work surface of the agar.
