Aluminum Crimp Caps | Steel Screw Caps | Range of Septa| Magnetic
Caps used in Headspace Analysis are historically, crimp style. 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.
Different cap styles such as magnetic caps, pressure relief caps and standard crimp caps are available. *We offer almost every type of septa including: septa with aluminum foil, black rubber, blue rubber, butyl rubber, butyl rubber/PTFE, dark grey rubber, grey rubber, low bleed silicone rubber/PTFE, molded rubber, natural rubber, orange rubber, pre-slit septa, red rubber, silicone rubber/PTFE (Most Popular), translucent rubber and septa for SPME.
To properly select a headspace cap/septa will depend on the autosampler you are using and the amount of headspace pressure that is going be generated.
