Chromatography Autosampler Vial Caps Only
Microsolv Technology Corporation Caps, Headspace, Crimp Top, with Grey Butyl Rubber / Partially Laminated PTFE Septa, fitted in Aluminum, Silver Pressure Relief Caps with 8mm center holes. Pharma-Fix. For use with 20mm Crimp Top Headspace Vials. 100/PK.
Shaped, Butyl Rubber with Durometer of 50 Shore A, (hardness) and 3.0mm thick. Partially laminated with PTFE only on the light grey side of the Septa that faces the sample area. Butyl Rubber facing the glass vial provides a very good seal, due to its elasticity. Combining inertness of PTFE and elasticity of Butyl Rubber. This type of Septa is commonly known as Pharma-Fix™ and is temperature resistant from -40⁰ to 120⁰C. Clear lacquered Caps have score lines that will break open at 3.0 +/ 0.5 Bar, for safety. Low cost for budget minded laboratories.
