Microsolv Technology Corporation Septa, 20mm, Headspace, Molded, Grey Butyl Rubber / Light Grey Rubber with Laminated PTFE. For use in 20mm Crimp Caps, sold separately. Pharma-Fix type Septa. 1000/CS.
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. 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. Use in Aluminum or Steel Crimp Caps for Headspace autosamplers. Supplied in Polyethylene Bags.
Microsolv Technology Corporation Septa, 20mm, Headspace, White Silicone Rubber / White PTFE. For use in 20mm Crimp Caps, sold separately. Ultra Low Bleed. 1000/CS.
Silicone Rubber / PTFE Septa with Durometer of 45 Shore A, (hardness) and 3.0mm thick with Ultra Clean PTFE and Ultra Low Bleed Rubber is good for highly sensitive analyses. The lower Durometer means that this is a softer Septa and therefore better for easier penetrations by autosampler needles. Wide temperature range from -60⁰ to 200⁰C. Use in Aluminum or Steel Crimp Caps for Headspace autosamplers. Supplied in Polyethylene Bags.
