Certified screw-top autosampler vials for HPLC, UHPLC and LC-MS
Screw-top vials are the everyday choice for HPLC and LC-MS: the thread lets a vial be opened and re-closed without a tool, which makes them the preferred format for standards, for re-injection and for any workflow where the vial is handled more than once.
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
