DiamondPure 2 mL Chromatography Vials, 12x32 mm Clear & Amber Glass, Screw/Snap/Crimp Closure — 100/Pack
The DiamondPure Chromatography Vial is a 2 mL, 12x32 mm glass autosampler vial engineered for HPLC, GC, and LC-MS workflows where injection reliability and low extractables matter. Each vial features a large opening for unobstructed needle access and a white marking spot for fast sample identification. Clear glass suits routine assays; amber glass protects light-sensitive analytes during extended sequence runs.

Frequently Asked Questions
What closure types are offered, and which septa fit them?
Three formats are available: 9 mm screw, 11 mm crimp, and 11 mm snap. Match your cap and septum to the closure style — screw caps thread on, crimp caps require a crimper, and snap caps press on by hand.
When should I choose amber glass over clear?
Select amber glass for light-sensitive analytes, photodegradable pharmaceuticals, or long autosampler queues under tray lighting. Clear glass is preferred when visual fill inspection or particulate checks are needed.
What does the white marking spot provide?
The white write-on spot lets analysts label sample IDs, dates, or batch codes directly on the vial without adhesive tags, reducing tray confusion during long sequences.
Are these vials compatible with standard autosampler racks?
Yes. The 12x32 mm footprint is the industry-standard 2 mL format and fits common autosampler trays from major instrument platforms across the 9 mm and 11 mm options.
