DWK Life Sciences (Wheaton) E-C Sample Vials, Black Phenolic Caps with PTFE/14B Rubber Liners
By DWK - Wheaton Science ProductsClear and amber glass vials have closed-top screw cap closures with PTFE faced 14B white styrene-butadiene rubber liners. In these vials, PTFE and type 1 glass are the only surfaces that will make contact with your sample, so that this sample vial and closure combination provides an extremely inert and chemically resistant environment for harsh, sensitive and reactive materials. Both caps and the liners are autoclavable.
