These clear screw thread EPA vials for the collection and storage of water samples comply with the guidelines for establishing test procedures for the analysis of pollutants (Ref. EPA Methods 601, 602, 603 and 604). While vials are not "pre-cleaned," they are packaged in a plastic shrink wrap module, lehr-clean, as they come from the end of the production lehr and then are placed into a corrugated shelf-pack. Open-top closures and PTFE-faced silicone septa or solid-top PFTE-faced white rubber-lined closures are available separately. Clear EPA vials are manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements.
