Buying Guide
How to choose screw cap glass vials fast and confidently:
- Material and compatibility: Look for borosilicate glass for chemical resistance and temperature tolerance. Check liner material for leak protection with your liquids.
- Cap design: PE liners and tight-threaded caps minimize evaporation and leakage. Consider extra PE pads or gaskets for aggressive solvents.
- Capacity and dimensions: Choose sizes that fit your storage needs and space. Note mouth diameter for easy filling or dispensing.
- Temperature handling: If you need freezing or heating, confirm the product’s documented temperature range.
- Purity and safety standards: For lab use, products that meet USP Type I or similar standards offer lower extractables and higher reliability.
- Bulk vs. individual use: Bulk sets are cost-efficient for frequent use; single sets are convenient for drafts and fieldwork.
