Protecting light-sensitive samples during chromatography, the 2mL Amber Glass Vial with 9-425 Screw Cap uses Type I Borosilicate glass. This material resists chemical degradation and maintains sample integrity. Standard 12x32 mm dimensions fit most HPLC and GC autosamplers found in research facilities.
Key Features
- UV Light Protection: 12x32 mm Type I Borosilicate glass with amber tinting. Light-sensitive chemicals remain stable.
- Chemical Resistance: High-purity glass construction prevents leaching or pH shifts. Material withstands harsh laboratory solvents.
- 9-425 Screw Thread: Standard neck profile fits Agilent and Shimadzu autosamplers. Hardware aligns without mechanical errors.
- PTFE/Silicone Septa: Polypropylene cap with chemically inert liner material. Despite road dust, samples stay pure.
Frequently Asked Questions
What is a 9-425 screw thread vial?
This indicates a 9mm diameter opening with a specific thread pitch. The standard fits most modern robotic autosamplers.
Why use amber glass for lab samples?
The amber tint filters ultraviolet light to prevent sample breakdown. It protects compounds that degrade under laboratory lighting.
