Import Crimp Headspace Nd20 — Buy in Bulk from Supplier in China

The Crimp Headspace ND20 is a sealed vial designed for headspace sampling of volatile organic compounds. It offers three internal volumes - 6 ml, 10 ml and 20 ml - each available in clear or amber glass. The vial features a flat bottom to ensure stable positioning during heating. The supplier lists the vials as “rounded‑flat” and suitable for gas‑chromatography analysis after gasification.

Standard headspace vials are made from borosilicate glass, providing chemical resistance and thermal stability; this is typical for the category. The cap normally incorporates a PTFE liner and a screw‑on mechanism, which is a common sealing method for maintaining sample integrity. Typical dimensions for a 6 ml vial are roughly 20 mm in diameter and 70 mm in height, with proportional scaling for larger volumes. The ND20 series conforms to these industry dimensions and is compatible with most commercial GC headspace autosamplers.

Laboratories performing environmental monitoring, food safety testing or pharmaceutical stability studies frequently purchase these vials. Buyers usually request bulk packaging, often in cartons of 250 or 500 units, and negotiate Incoterms such as FOB Hangzhou. Exact minimum order quantities, pricing and lead times are not disclosed in the listing, so interested importers should contact the supplier directly for confirmation.
