Sample Vials in Lab File with Open Top Caps and Septa-WTN 225170

Clear glass vials with open top closures and septa. The open-top closures have PTFE faced silicone septa assembled in the cap. The cap material is black phenolic. With these organic vials, PTFE and type 1 glass are the only surfaces that will make contact with your sample. This sample vial and closure combination provides an extremely inert and chemically resistant environment for harsh, sensitive and reactive samples. The Vial File™ provides a compact, readily accessible means of sample storage. The vials are stored in individual partitions within a plastic clear case. The case is made from polystyrene with hinged lids and alphanumerical indexing. Foam inserts provide extra protection for the vials. Vial Files™ come with vials manufactured from WHEATON 33® low extractable borosilicate glass (meets ASTM Type I Class A and USP Type I standards) to protect pH balance and sample integrity.
