20ml Crimp GC Vial for Lab Test
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.
The crimped top headspace vial is made of Type 1 borosilicate glass. Clear glass bottles with 20mm crimp sealing surfaces are designed for most headspace autosamplers. The flat-bottom vial can maximize heating efficiency when used in conjunction with the bottom. The robotic arm that lifts the robotic arm from the pallet can handle round-bottomed sample vials more easily.
