screw and crimp caps with PTFE for GC vials

These 20mm Crimp Top Aluminum Caps are typically made of aluminum, which is a lightweight and corrosion-resistant metal. Aluminum provides excellent sealing properties, ensuring the integrity of the sample within the vial. The cap features a crimp top design, which means it can be securely attached to the vial by using a crimping tool. This process involves crimping the cap around the vial’s neck, creating a tight and tamper-evident seal. The design with a 9.5mm hole in the center of the cover can be used for headspace analysis. Standard GC and HPLC sample bottles can be used for autosampler and sample storage.  20mm Crimp Top Aluminum Caps often come in various colors, which can help with sample identification, organization, or differentiation of different products or solutions.

Advances in glass vial manufacturing now produce the type of threads that are needed to properly seal the vial and cap under pressure, producing a Screw Top Headspace System that works well together.

Headspace vials are a kind of laboratory vials for top space analysis, with the features of high-temperature resistance and corrosion resistance. A headspace vial is used in the process of GC  chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial. The material of Headspace Vials is low extractable Borosilicate glass with a low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance, and high chemical stability. Headspace Vials are suitable for headspace analysis of volatile solids and gases.

headspace vials come in two basic sizes :10 mL glass vials and 20 mL glass vials; Crimp caps are most common however many customers use screw sample and application dependent; clear glass vials and amber vials are available
