Wholesale Petri dish For Sale in China

Petri dishes are used in a variety of applications, primarily in laboratories, including:

Petri dishes are used to grow microorganisms while separating them from air pollutants. They provide a controlled environment for these organisms to grow, which can then be used for further research or testing.

Antibiotic susceptibility testing: Petri dishes, agar, and antibiotic trays can be used to test the effectiveness of different antibiotics on bacterial cultures and select the correct antibiotic treatment.

It can be used as a support for further study of the sample anatomy.

Petri dishes can be used to grow animal and plant cells, allowing researchers to observe cell growth and behavior under controlled conditions.

·Laboratory Safety: Helps separate individuals from unknown germs that can easily spread and cause disease.

For example, it is used in schools and universities to observe the germination of seeds.

Petri dishes come in all shapes, sizes, and materials. The choice of Petri dish to be used depends on the specific application and the needs of the laboratory. Here are some common Petri dish types:

Size: varies in size from a few millimeters to a few centimeters in diameter;

The saucer is 35 mm in diameter.

60 mm

90mm is the most commonly used size in microbiology.

·100mm petri dish, used for cell culture of larger bacterial colonies and tissue culture experiments.

• The maximum size is 150mm, used for culturing large colonies or cell cultures, such as plant cells or yeast.

Shape: Petri dishes are usually round, but some specialty petri dishes may have other shapes. The shape of the Petri dish is chosen by the researcher according to the specific requirements of the experiment:

Round Petri dishes are the most common shape.

The shape of the square.

Rectangular shape.

Materials: Petri dishes can be made from a variety of materials, including:

Glass: Borosilicate glass is usually used. Glass Petri dishes are durable and can be sterilized by heat, chemical sterilization, or radiation. They are usually reusable and have a smooth, non-porous surface that is easy to clean. Glass Petri dishes are useful for applications that require high temperatures or harsh chemicals, and they are often used in research and academic environments.

Polystyrene: Polystyrene Petri dishes are lightweight, disposable, and inexpensive. They are widely used in routine microbiological testing in clinical and industrial settings. Polystyrene Petri dishes have different surface treatments, such as tissue culture treated, untreated, or low adhesion, to promote cell attachment or prevent cell attachment, depending on the application.

Polypropylene: Polypropylene Petri dishes are more resistant to heat and chemicals than polystyrene Petri dishes. They are also lighter and more durable than glass Petri dishes, making them a popular choice for field work, environmental testing, and industrial applications.

Cellulose Acetate Petri Dish: Cellulose acetate Petri dishes have a higher air permeability than other types of Petri dishes, making them suitable for applications requiring high oxygen or carbon dioxide levels. They are also resistant to many chemicals and can withstand high temperatures.

Surface: Petri dishes can have a smooth or textured surface. Textured surfaces can promote the growth of certain microbes or help prevent bacterial buildup.

Lids: Lids for Petri dishes can be solid, vented, or semi-permeable. Vented lids allow gas exchange and are useful for the growth of anaerobic microorganisms, while semi-permeable lids control humidity levels in the dish.

Stackable Petri Dish: This type of Petri dish has multiple compartments that can be stacked together, allowing efficient use of space in crowded laboratory settings.

Slices: Some Petri dishes have slices or compartments that allow the use of multiple types of media on a single plate or the testing of multiple samples at once.

Coated culture dishes are culture dishes that have been treated with a layer of material (such as collagen, fibronectin, laminin, or extracellular matrix proteins) designed to promote cell attachment and growth.
