Amber 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).
Amber EPA vials, for light sensitive solutions, are fabricated from amber 203 borosilicate glass.
Open top closures and PFTE-faced silicone septa or solid top PFTE-faced white rubber-lined closures are available separately.
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. They are then placed into a corrugated shelf-pack.
EPA 40 CFR 136 "Guidelines for Establishing Test Procedures for the Analysis of Pollutants" and EPA 40 CFR 141 "National Interim Primary Drinking Water Regulations; Control of Trihalomethanes in Drinking Water" and recommends the use of 28 x 95 mm vial for discrete water sampling. KIMBLE also offers the specified open-top closures (73804 and 73806A) as well as the PTFE-faced silicone rubber septum (73818A).
