For example, 8-425 neck finish represents a vial with a diameter of 8 mm across the outside of the threads and a thread style of 425. Screw thread vials and caps are more expensive than crimp seals. Caps for screw thread vials are available with either an open hole for autosampler use and standard addition or with a solid top for sample storage.

18mm Screw top headspace vials, caps, septa. Our screw top headspace vials are a novelty in a crimp-neck dominated field. They provide a ready-to-use, convenient solution that does not require crimping or decrimping tools. Headspace vials, septum and caps can be purchased in various quantities separately or as convenience kits.

Crimp Top Vials Crimp top vials provide the best seal of any vials. Crimp top vials also have a large opening finish (6.0mm) and are available in both clear and amber glass, with and without marking spots on the vial. Snap Top Vials These vials are ideal for high throughput analyses. The polyethylene caps used with snap top vials offer a positive

secure seal Two neck lengths are available Flat or rounded bottom designs Beveled neck vials are available in both 10 mL and 20 mL capacities, flat or rounded bottom. The 20 mm crimp caps provide a consistently secure seal. Flat-bottom headspace crimp top glass vials (2714Q19, Q20) 20

Thermo Scientific™ 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.

Naturally, choice is up to the end user and instrument requirements. Some instruments require magnetic seals, and unless there has been a recent introduction of a magnetic screw cap vial in a 1-2mL volume, crimp vials would be required. As for sealing properties, if sealed properly, I see no advantage of one over the other.

GC Vials ND18 headspace 20ml (Screw Vials) No risk of incorrectly sealed vials as is the case with crimping. More convenient to close and open, especially as magnetic crimp caps are very hard to crimp . Lower coring and protection for the needle due to thinner septa. Universal use for Headspace and SPME due to thinner septa

the gas phase (headspace) for analysis. QEC vials consist of Type 1 borosilicate glass with crimp or screw thread finishes, manufactured to provide uniform glass thickness, which ensures even heat distribution for sampling reliability. QEC headspace products meet or exceed OEM instrument manufactur-ers' specifications.
