What the AI looks for in Lab Sample Vials
- Glass grade
- Type I borosilicate for chemical samples; soda-lime is acceptable only for dry or non-reactive storage Leaching and pH drift from soda-lime can compromise stored samples.
- Cap finish and liner
- Match the finish exactly; use PTFE-faced liners for solvents and acids The seal and chemical compatibility depend entirely on the closure.
- Cleanliness certification
- Use pre-cleaned vials with a certificate of analysis for trace or regulatory work Residues on uncertified vials can show up as contamination in low-level analyses.
- Amber vs clear
- Amber for light-sensitive samples Amber glass blocks the UV that degrades photolabile compounds.
Brands that matter
- Kimble: DWK brand with established borosilicate sample vial lines.
- Wheaton: DWK brand with a wide range of vial sizes and closures.
- Qorpak: Many screw-thread vial and liner combinations.
- Thermo Scientific: Includes the I-Chem pre-cleaned environmental vials.
What to avoid
- Vials sold without a stated glass type or cap finish
- Unlined caps for anything volatile or corrosive
