Un-Assembled Aluminum Crimp Cap with PTFE/Butyl (Red) Septa and Star Spring, 100/pk. For sealing sample vials for temperatures up to 130°C. Very low background peaks, lowest permeability, not recommended for repetitive injections from the same vial or for storage. true false. Part Number.

A specially moulded seal with a PTFE insert. Sealing surface of Butyl and PTFE affects a more positive seal than non-PTFE-faced septa. Ideal choice for temperatures below 125°C. Good sealing characteristics, excellent resistance to most solvents with reduced coring and high puncture tolerance.

Type 1 borosilicate glass Clear glass vials with 20mm crimp seal finish are designed to fit most headspace autosamplers Flat bottom vials maximize heating efficiency when used with bottom Round bottom vials are more easily handled by robotic arms that lift the vial from the tray
