EPA (VOA) vials meet or exceed EPA standards for volatile organic analysis. Clear or amber vials are available in 20, 40, and 60 mL sizes. Order polyproplene screw caps or SURE-Clean caps separately.
In 42 ml glass vials, diluted extract is buffered to a pH of 4.5 – 5.0 and treated with Sodium Tetraethylborate (NaTEB), resulting in ethylation of oxidized mercury species. These volatile ethylated species (as well as elemental mercury) are stripped from the liquid

11mm Snap Cap Vials for Aijiren. Aijiren Vials manufactured of Clear, Type 1 Class A or Amber, Type 1 Class B, borosilicate glass. Aijiren Vials have a standard graduated write-on patch for easy filling and identification. Snap caps used with the Aijiren Vial system are a convenient alternative to aluminum seals.
In an environmental analysis context, the VOC designation, or volatile organic contaminants , generally refers to the analysis of compounds in environmental samples with the following chemical properties:+. Low boiling points (below 200°C) Low vapor pressures. Low-to-medium water solubility. Organic
This kit enables measurement of the volatile organic carbon (POC) driven from the sample during the sparging process at room temperature. Nitrogen carrier gas kit High-purity nitrogen gas (max. 1 ppm of each CO, CO 2 and HC) can be used as the carrier gas.
