National Headspace Vials
* Superior quality 1st hydrolytic class glass (Type 1)
* Headspace vials are available with either a round or flat base
* Round bottom vials are compatible with most autosamplers and more easily handled by robotic arms that lift the vial from the tray
* Flat bottom vials maximize heating efficiency in manual headspace sampling and are required for use in some instrument models
* Vials feature beveled or square edge finish
* The bevel edge on the lip of the vial provides additional sealing power for greater leak resistance under high pressure

* Include matched quantities of vials and silver aluminum seals with pre-assembled septa
* Convenience kits save time during sample preparation
National 20mm Headspace Crimping and Decrimping Tools
* Crimping tools provide a reproducible, secure vial closure
* Manual decrimping tools allow easy removal of aluminum seals without breakage
* Decapping pliers are an economical choice for small quantities of vials
* Clean room crimpers and decrimpers can be autoclaved
