Thermo Scientific™ headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or with a screw-thread finish. Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs.

Choose septa materials to meet your needs.

• Gray Butyl Stoppers are an economical septum for lower temperature (125°C) or low-pressure applications.
• Gray PTFE/Red Rubber Septa are an economical choice where a PTFE barrier is desired.
• PTFE/White Silicone PurePack Septa for general volatiles analysis.
• Gray PTFE/Molded Black Butyl Septa offer a more positive seal against loss of fixed gases.
• PTFE/Blue High Purity Silicone Septum reduces background from extractables or outgassing of volatile contaminants.
• The Black Rubber septum is an economical choice for applications where reduced levels of vapor penetration are desired.

Unassembled convenience kits
National and Chromacol Headspace Unassembled Convenience Kits save time during sample preparation and include matched quantities of vials and silver aluminum seals with prefitted septa for added convenience.
