How to Choose the Best Strorage Vials

Solving Storage Challenges with F217 Liners

Screw thread vials are common for LC sample analysis as well as sample or standard storage. But is there a difference between autosampler vials and storage vials? Typically, autosampler vials used for LC analysis are 2 mL with a 9 mm screw thread, open top cap and septa. On the other hand, storage vials come in sizes ranging from 2 mL up to 32 mL, and the closures are typically solid top, lined caps with different threading.

2 mL Autosampler Vial vs. 2 mL Storage Vial

Both 2 mL autosampler vials and 2 mL storage vials are 12×32 mm in size. For most of our LC customers that prefer a screw thread vial, we recommend a 9 mm wide mouth vial, as they offer a 40% wider opening than the 8-425 screw thread vials. However, for storage of volatile compounds or long term storage (for standards, etc.), we recommend the smaller opening 8-425 option. The 8-425 vials have more threads per inch than the 9 mm vials, which keeps a tighter seal.
