GPI is abbreviation by the "Glass Packaging Institute". The GPI is duty for establishing and issuing standards for the types and finishes produced by American glass manufacturers. Aijiren as one of the largest chromatography consumables manufacturer, all of vials and septa, caps have get GPI certification.

In order to standardize the industry standard of chromatography vials, please referen:

8-425 neck thread vial is approximately 8mm in diameter across the outside of the threads. The 425 represents the style of thread.

Typical GPI specification found in the chromatography field are as follows:

8-425 Closure - Varian, Shimadzu

10-425 Closure - Waters Alliance 2690

13-425 Closure - Waters 48 position WISP™, Shimadzu

Note: 9mm thread finish does not appear in the GPI finishes. It is not a standard finish. The 9mm closure and vial are used with Agilent equipment.
