Frequently Asked Questions
What is the difference between flat-bottom and radius-bottom vials?
Radius-bottom vials distribute thermal stress more evenly during oven heating, reducing fracture risk in high-temperature headspace methods. Flat-bottom vials sit more stably in some racks. Both share identical neck dimensions and seal the same way.
Which caps fit these vials?
Crimp-top variants use standard 20mm aluminum or magnetic crimp caps with PTFE/silicone septa. The 9050020RB screw-top variant accepts 18mm CTC-compatible magnetic screw caps. Caps and septa are sold separately.
Are these vials compatible with automated headspace samplers?
Yes. The 22.6 mm outer diameter and standardized neck finish fit common platforms such as Agilent, PerkinElmer, and Thermo headspace autosamplers using 20mm crimp or 18mm magnetic screw closures.
How many vials come per pack?
Each pack contains 100 vials per box, priced per box. Lot numbers on each box support documentation requirements for accredited workflows.
