Import 20mm Headspace Crimp Top Vial — Buy in Bulk from Supplier in China

This 20mm Headspace Crimp Top Vial (model HM-0838A) is a 10ml capacity laboratory vessel manufactured from borosilicate glass, featuring a flat bottom configuration and amber coloration designed for light-sensitive sample storage. The vial measures 22.5mm in diameter and 46mm in height, with a 20mm crown finish compatible with standard crimp-style closures. The product listing indicates the material is borosilicate glass conforming to USP Type 1 specification, though this should be verified with the supplier as the listing notes 'to be confirmed'. The vial comes without pre-printed labels or graduation scales, offering a blank surface for customization.

The vial is designed for headspace analysis applications and is manufactured to serve as a direct replacement for several major chromatography instrument brand vials, including Agilent part numbers 5182-0838 and 5182-0837, La-pha-pack catalog numbers 20 09 0795 and 20 09 0796, and Thermo Scientific models C4020-10 and C4020-20. Borosilicate glass provides excellent chemical resistance and thermal shock tolerance, making it suitable for volatile organic compound analysis and gas chromatography applications. The flat bottom design ensures stable positioning in automated sample trays and rack systems. Packaging is standard at 100 pieces per box as the minimum order quantity, with the supplier offering optional customization services for logo printing, writing labels, and graduation scales.

This product targets laboratories, pharmaceutical quality control departments, environmental testing facilities, and chemical analysis service providers requiring reliable sample containment for headspace gas chromatography. The primary buyers include analytical instrument service companies, contract testing laboratories, and research institutions conducting volatile compound analysis. The listing provides compatible accessory part numbers for caps, septa, crimpers, and decappers, enabling purchasers to source complete sample preparation kits from a single supplier. Import considerations include verifying the USP Type 1 material certification, confirming dimensional tolerances for automated handling compatibility, and establishing lead times for both standard and customized orders.
