These volatile organic analysis (VOA) vials are made of borosilicate glass. Choose from an open-top cap (0.125 thick PTFE/silicone septa) or closed-top style cap in a variarty of capacities and clear or amber glass.Water sampling vials are ideal for water sample collection and storage when testing for pollutants. To meet EPA standards and prevent contamination, vials are prepared in a solvent
VOA Vials or borosilicate glass vials KaptClean® for Volatiles are designed for EPA volatile organic analysis (VOA). This method is also known as Protocol B. Volatiles are chemicals that have high vapor pressures at room temperature (easily evaporate).
VOA Vials - Amber Screw Thread, Cleaned for Volatiles. Amber VOA Vials or borosilicate glass vials KaptClean® for Volatiles are designed for EPA volatile organic analysis (VOA). Volatiles are chemicals that have high vapor pressures at room temperature (easily evaporate). They can include benzene, chloroform, toluene and carbon tetrachloride.
To meet EPA standards and prevent contamination, vials are prepared in a solvent-free facility. Test for toxicity with clear, white, or amber vials for ultraviolet sensitive samples. Since water sampling procedures demand immediate testing for accurate results, open-top, closed-top, attached, or screw on cap options permit quick access to contents.

VOA Vials - Clear Screw Thread, Cleaned for Volatiles. Clear VOA Vials or borosilicate glass vials KaptClean® for Volatiles are designed for EPA volatile organic analysis (VOA). Volatiles are chemicals that have high vapor pressures at room temperature (easily evaporate). They can include benzene, chloroform, toluene and carbon tetrachloride.
To measure dissolved gases, 40 ml of groundwater samples was collected in precleaned volatile organic analysis (VOA) vials with no headspace and stored upside down at 4°C until analysis. To minimize diffusion of oxygen into the VOA vials through the septa, samples were analyzed within 5 days.
COMPANY : COLEPARMER,U.S.A These glass vials are precleaned to meet strict EPA requirements. Vials with certificate of analysis meet EPA criteria for more than 60 volatile organic analyses (VOA). All vials include a polypropylene cap with a 1/8 inch PTFE-faced silicone septum.
The screening method is a modification of the EPA medium level VOC soil analysis and includes soil sample preservation and extraction into methanol with subsequent analysis of an aliquot of the extract headspace equilibrium over 30 ml of water in a 40 ml VOA vial. Total analysis time per sample was under 20 minutes.
