20 mm crimp seals — standard, magnetic and pressure-release
20 mm aluminium and bi-metal crimp seals for headspace vials, with PTFE/silicone or PTFE/butyl rubber septa. Pressure-release designs vent safely when a vial is heated; magnetic versions suit magnetic-transport autosamplers.
Key features
- Type 1 Class A borosilicate glass — 33-expansion clear, 51-expansion amber — with low ion content to minimise sample loss and contamination
- Critical dimensions inspected by machine-vision cameras and gauges, so vial, cap and septum fit the autosampler every time
- 100 % traceable through manufacture; a Certificate of Conformance is available by lot number
- Clean-room packaged to keep particulates out of the vial
- Certified for UHPLC, HPLC, GC, SFC and MS analysis
