Sample Vials, Borosilicate Glass, with Attached Closures, Wheaton
Vials feature attached black phenolic closures. These solid-top, screw-thread closures are lined with PTFE-faced 14B white styrene-butadiene rubber. The externally-threaded vials and matching closures are autoclavable. This sample vial and closure combination provides an extremely inert and chemically-resistant environment for harsh, sensitive, and reactive samples. Vials are manufactured from borosilicate glass (meets ASTM Type I Class A and USP Type I standards) to protect against changes in pH and maintain purity of contents. Choose from clear or amber colored vials.
