Lab Sample Vials

Choose based on chemical compatibility and sample type: glass (borosilicate) is best for organic solvents and long-term storage, while polypropylene or HDPE plastics resist many aqueous reagents and are more impact-resistant; check compatibility charts for specific solvents and temperatures

Select size by sample volume and headspace needs—common sizes range from 0.5 mL to 20 mL—and pick closures (screw cap, crimp, snap cap) with appropriate liners or septa for sealing, pressure resistance, and analysis method compatibility

Yes: borosilicate glass vials and certain high-grade plastics are suitable for elevated temperatures, while specialized cryovials made from specific polypropylene blends and leak-resistant caps are designed for low-temperature storage; confirm rated temperature limits from specifications

Clean with appropriate solvents and detergents, rinse with deionized water, and dry thoroughly; avoid abrasive brushes on coated glass, and store vials capped in a dust-free environment to prevent contamination and maintain integrity

Look for consistent dimensions/tolerances, low extractables and leachables, certified cleanliness or pre-rinsed options, compatible septum/lid materials, and any documentation such as material specifications or lot traceability

Per-unit costs generally decrease with larger pack sizes; expect a range from budget options under $50 for small packs to higher per-unit quality products in larger lab packs, so balance required cleanliness, material, and quantity needs

Plastic vials are suitable for some LC applications but are generally not recommended for gas chromatography when volatile organic solvents or high temperatures are involved; glass vials are the standard for GC due to temperature and solvent compatibility
