- Clear borosilicate glass with a 0.125” septa
Borosilicate glass vials come with a standard 0.125 in. thick, I-CHEM blue, PTFE/silicone septa in an open-top 24-414 polypropylene cap.
The I-CHEM molded-in septa retainer ring holds the septa securely in place without bonding to the cap, so septa can be removed and replaced as needed.
I-CHEM Certified® 200 and 300 series bottles are guaranteed to meet the EPA’s Performance Based Specifications for Volatile Organic Analysis.
