- The Environmental Protection Agency (EPA) is responsible for monitoring of analytical standards used for environmental analysis in the USA.
- Much of this analysis is applied to the testing of water supplies for the presence of potentially harmful chemicals.
- These chemicals include pesticides, herbicides and polycyclic aromatic hydrocarbons. (PAH)
- The collection and processing of these water samples has been controlled by defining the type of vials used for this stage of the analysis.
- The EPA Vials are defined by their size, volume and their degree of cleanliness.
- These EPA Vials are also referred to as VOA (Volatile Organic Analysis) vials.
EPA VIALS PROVIDE:-
- Two sizes available in clear or amber neutral glass.
- Standard 28mm o.d. with heights of 57mm (20mL) and 95mm (40mL)
