Glass Sample Vials with Screw Cap

Glass Sample Vials with Screw Cap

Pack of 100 borosilicate glass sample vials with blue polypropylene screw caps and silicone gasket liners, suitable for general laboratory sample storage, chemical reagent containment, chromatography sample preparation, environmental testing, and biological sample archiving. The wide-mouth threaded opening allows easy pipetting access, and the PP screw cap with integrated silicone gasket provides reliable, leak-proof sealing across a wide range of aqueous and polar organic media. Clear vials allow direct visual inspection of stored contents without opening the container. Amber vials block UV and visible light, protecting photosensitive samples such as light-sensitive reagents, biological extracts, fluorescent compounds, and analytical standards from photodegradation. Available in sizes from 2 mL to 60 mL to accommodate a broad range of sample volumes. Made from borosilicate glass with good chemical resistance and thermal durability; vials are reusable and compatible with standard laboratory cleaning protocols.

COMMON APPLICATIONS: General-purpose liquid and solid sample storage in chemistry, biology, and environmental labs; chromatography sample preparation and fraction collection; reagent and standard solution storage; environmental water and soil sample archiving; light-sensitive compound storage (amber vials).

USAGE NOTES: Caps should be finger-tightened firmly to ensure a leak-proof seal – do not overtighten. Compatible with common laboratory solvents, aqueous buffers, and dilute acids and bases. For aggressive organic solvents, confirm compatibility with the PE gasket liner before extended storage use. Vials are reusable; clean with standard laboratory detergent and rinse thoroughly before reuse.
