Headspace vials are available in several sizes (5-27 mL) and styles in clear or amber glass. The most common sizes are 6, 10 and 20 mL. The style and diameter of headspace vials will depend upon your autosampler.
The top finish of the vial can be a flat top or beveled finish. Using a beveled finish vial reduced the amount of sealing surface between the crimp seal and the glass surface
Compatible with all 9 mm screw-thread vials. Molded, 10-mil, solid pierceable cap. PTFE-free—ideal for PFAS analysis (e.g., EPA 537) and other PFAS-sensitive methods. Note: Polypropylene vials and caps prevent sample contamination from PTFE coated septa. However, since polypropylene caps do not reseal, evaporation occurs after injection.
Vials, screw top with black polypropylene hole cap (10-425 thread), large opening, pre-assembled. 6 Product Results
