The Petri dish, named after German bacteriologist Julius Richard Petri, is a shallow cylindrical glass or plastic-lidded word biologists use for cell culture. Usually partially filled with warm liquid containing agar, the dish is inoculated (“plated”) with a microbe-laden sample.
Penicillin, the first antibiotic, was discovered in 1929 by Alexander Fleming when he noticed that mold that had contaminated a bacterial culture in a Petri dish killed the bacteria around it.
Pre-poured
A sterile petri dish is a shallow, glass, or plastic cylindrical dish biologists use to culture cells. The word is named after the German bacteriologist Julius Richard Petri (1852-1921), who invented it while working as an assistant to Robert Koch in 1877.
Today, the dish has become one of the most common lab items biologists use. In a standard laboratory, a Petri dish is filled with a growth medium called agar, which contains nutrients, blood, salt, indicators, antibiotics, and other substances that promote the growth of microorganisms like bacteria and fungi.
Sterile Petri Dishes are manufactured from medical-grade virgin polystyrene and feature a flared lid skirt and squared corners to allow easy one-hand operation. They also have ventilation ribs which allow air circulation and reduce condensation during incubation. They also have a consistently flat surface for even media distribution. They are available in various styles, rims, compartments, and designs to suit your needs.
Optically clear
A Petri dish is a type of container that is used for culturing bacteria. These dishes are made mainly from plastic and have a lid that protects lab samples from contamination.
In 1887, bacteriologist Julius Richard Petri invented this device as an assistant to his mentor Robert Koch. It is a shallow, circular vessel with a clear lid that protects laboratory samples while allowing observation under a microscope.
They are typically filled with agar media that is prepared from red algae. Agar contains blood, salt, antibiotics, and other nutrients that promote microbial growth.
Petri dishes can also store liquid, granular, or powdered samples. Their flat profile and transparency make them convenient for temporary storage. They are also commonly used as receptacles for viewing samples under a microscope without removing the dish’s lid.
DNase and RNase free
A sterile petri dish is a glass or plastic cylinder with a lid to retain a thin agar coating for microbiological culture. It is a widely-used laboratory tool named after German bacteriologist Julius Richard Petri (1852-1921).
These dishes are commonly used in laboratories to cultivate bacteria, yeasts, and molds. They can be made from either borosilicate glass or polystyrene plastic.
Typically, glass Petri dishes are reusable, while plastic Petri dishes must be discarded after use. Both types have their pros and cons.
Generally, glass Petri dishes are made from borosilicate glass, while plastic ones are usually made from polystyrene or polycarbonate. Both are heat resistant, but the glass type can be sterilized in an autoclave for repeated use.
Non-toxic
Sterile Petri dishes are a valuable tool for scientists in biology and chemistry. They are used to cultivate bacteria and other microorganisms and observe seeds’ germination.
They are also used to test antibiotics and help determine if they will kill a specific strain of bacteria. The Petri dish has a thin layer of agar and is usually covered by a cover to prevent the agar from coming into contact with other organisms.
These disposable plastic dishes are ideal for all types of culturing where accurate bacterial count or microscopic examination is required. They are sterile (gamma sterilized) and can be reused many times.
These sterile plastic Petri dishes are manufactured from virgin polystyrene under controlled conditions of low bioburden and high optical clarity. They have distortion-free lids and consistently flat bottoms to save media. They are compatible with most industrial and non-industrial automatic agar-pouring machines. The covers feature ventilation ribs to allow free air.
