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.
