Description

A specimen jar, also known as a gas jar, PS (polystyrene) is a laboratory container used to store, transport, and examine solid or liquid specimens. It is made of polystyrene, a type of plastic that is known for its low cost, transparency, and durability. The jar has a cylindrical body with a tight-fitting lid that seals the contents, which can be viewed through the transparent walls of the jar.

Gas jars are commonly used in laboratory settings for a variety of applications, including storage and transport of specimens, examination of live insects, or for studying the behavior of gases in a closed system. They are available in various sizes, ranging from small jars for small-scale experiments to large jars for large-scale operations.

The polystyrene construction makes the jar suitable for use in applications where glass is not appropriate, such as with light-sensitive materials or when working with hazardous chemicals. Gas jars are also easy to clean and can be used repeatedly, making them a popular choice for laboratory use.
