Petri Dish

  • A Petri dish (sometimes spelled "Petrie dish" and alternatively known as a Petri plate or cell-culture dish), named after the German bacteriologist Julius Richard Petri,[1][2] is a shallow cylindrical glass or plastic lidded dish that biologists use to culturecells[3] – such as bacteria – or small mosses.[4]

  • Modern Petri dishes usually feature rings and/or slots on their lids and bases so that when stacked, they are less prone to sliding off one another. Multiple dishes can also be incorporated into one plastic container to create a "multi-well plate". While glass Petri dishes may be reused after sterilization (via an autoclave or one hour's dry-heating in a hot-air oven at 160 °C, for example), plastic Petri dishes are often disposed of after experiments where cultures might contaminate each other.

The Petri Plates range is large. Indeed CLS adapt to every needs of its users and propose by the way round plates, squares, contact with or without vents. The advantage of CLS’s Petri plates is the compatibility with most industrial and non-industrial automatic agar-pouring machines. Petri plates are manufactured under aseptic conditions according to “clean room technology”

Cell Culture

In microbiological and biochemical engineering studies, one almost always deals with a pure culture or a mixture of known cultures, except perhaps in wastewater treatment studies. Unless aseptic culture techniques are followed strictly, an originally pure culture will definitely become contaminated with other unwanted species. For illustrative purposes, an extraterrestrial who has never seen a human being simply cannot accurately study human behavior if the group of subjects to be observed includes, in addition to humans, monkeys, dogs, cats, and many more other "contaminants." The results of such a study will certainly be unreliable. Similarly, the use of a contaminated culture with unknown microorganisms will only lead to incredible results that are of little value. Thus, the isolation and maintenance of a pure culture is of utmost importance in many microbiological studies.
It is especially important to work with a well characterized strain if the microorganism is used for food preparation, as well as in antibiotic production where the product is to be taken internally. For the same reason that a student will not lick an incubated plate that was exposed to the air, the presence of a large number of contaminants may present a potential health hazard, especially when the exact natures of the contaminants are unknown. Licking that agar plate probably will not kill the student; however, the probability of fatality certainly increases with higher numbers of organisms. Conversely, the probability of a wasted fermentation run due to contamination is directly proportional to the number of microorganisms in the environment, which in turn is directly related to the cleanliness of the laboratory.
The need for a clean working environment in biochemical engineering studies must be stressed again, for cleanliness is the prerequisite to any meaningful work. (This obsession is not the result of the instructor having had bad toilet training as Sigmund Freud may have concluded.) As demonstrated by the plate transfer process, many parts of the aseptic procedures require occasional exposure to the surrounding environment. Since our laboratory cannot be made totally sterile economically, it is imperative that the room be kept clean. The use of a laminar hood, which creates an air curtain to reduce the chance of contaminants drifting into the working space enclosed by the hood, is highly recommended if it is available. However, a laminar hood itself must still be maintained in a clean condition.

CLS’ commitment+

These disposable conical-bottom and freestanding tubes feature easy-to-read graduations and smooth inner walls for easy filling and sample preparation. Rack-packed tubes are packaged in freezable, recyclable, autoclavable racks, and stackable rack designs make them ideal for benchtop organization. Caps are available in either flat or plug styles. Certain models are designed to provide protection for light-sensitive samples, manufactured from a dark polypropylene. These high-quality, high-performing centrifuge tubes are ideal for maintaining a secure seal when using shakers and horizontal incubators. 

FAQ+

As cells generally continue to divide in culture, they generally grow to fill the available area or volume. This can generate several issues:

Nutrient depletion in the growth media
Changes in pH of the growth media
Accumulation of apoptotic/necrotic (dead) cells
Cell-to-cell contact can stimulate cell cycle arrest, causing cells to stop dividing, known as contact inhibition.
Cell-to-cell contact can stimulate cellular differentiation.
Genetic and epigenetic alterations, with a natural selection of the altered cells potentially leading to overgrowth of abnormal, culture-adapted cells with decreased differentiation and increased proliferative capacity.
