EPA vial, also known as an Environmental Protection Agency vial, is a type of sample vial specifically designed for environmental analysis, particularly in the context of water and soil testing. The EPA has established certain standards and regulations for environmental testing, and EPA vials are designed to meet these requirements.
EPA vials are typically made of inert materials, such as borosilicate glass, to minimize interactions between the sample and the vial. They are available in different sizes, typically ranging from 20 mL to 40 mL, to accommodate various sample volumes.

Caps for screw thread vials are available with either an open hole for autosampler use and standard addition or with a solid top for sample storage. One piece polypropylene cap and membrane are also available. These pierceable screw thread caps are designed for one time use and reduce sample preparation time as there is no cap and seal to assemble.
