What vials are typically used in GC Headspace

Headspace Vials are manufactured from Type 1 borosilie glass, available in clear or aer. 51-expansion glass is typically used for headspace vials, although better-quality headspace vials such as those from gc headspace vials price, are made of 33-expansion glass. 33 is less likely to fracture if the vial is heated (the reason quality headspace vials are made of 33- expansion).
