The EPA vials are ideal for water sample collection for volatile organic analysis. The vials with unbonded septa have a molded-in retainer ring to keep septa firmly in place while allowing septa to be removed and replaced as needed. Also there are vials with the septum permanently bonded to the cap for secure sealing.Vials are available in all capacities, materials like plastic vials
Description Thermo Scientific Clear VOA Vials with 0.125″ Septa are designed for water sample collection for volatile organic analysis (VOA). Available with septum permanently bonded to the cap or unbonded for easy replacement.
Finally, the volatile compounds were eluted from the VCT using a 300‐μL mixture of MS‐grade n‐hexane and acetone (9 : 1), and the eluent was stored in 1.5‐mL glass vials at −20 C until its analysis
