VWR TraceClean 20 mL Clear Cylinder Glass Vials 72 ct. Laboratory Use Model: 89093-830

Type I clear borosilicate glass vials are for use in various analyses and in specimen, extract, and standards storage.

They are prepared in a solvent-free facility to prevent possible volatile contamination

Processed (PC) and Quality-Assured® (QA) vials follow EPA cleaning procedures listed in the OSWER Directive 9240.0-05A 'Specifications and Guidance for Contaminant-Free Sample Containers'. QA vials include a Certificate of Analysis in every case. QA vials also include bar codes with lot number and individual container number for complete traceability. Not Processed (NPC) vials do not receive the specialty cleaning process. All cases are custody-sealed to ensure content integrity.

Vials are available with polypropylene solid-top or open-top caps. Solid-top caps feature fluoropolymer resin liners. Open-top caps feature ultrasonically bonded 3.1 mm (¹/₈") fluoropolymer resin/silicone septa and are for volatile organic analyses.
