20mm Grey Molded Pharma-Fix Septa, PTFE/Butyl
Tight sealing and high analytical purity are essential in headspace applications, where elevated temperatures increase vial pressure. Noke Pharma-Fix septa use PTFE only in the central contact area to enhance sealing performance.Key Features
- Centrally Laminated PTFE : PTFE layer is applied only at the sample contact area, improving seal integrity while avoiding slipperiness of fully coated liners.
- Elastomeric Rim on Crimp Neck: Uncoated butyl edge rests on the vial’s glass neck, ensuring firm, reliable contact under pressure.
- Lamellar Molded Design: Side edges compress uniformly during crimping, creating a suction-like effect for consistent airtight sealing.
