1 DRAM Screw Thread Clear Glass Vial 13/425

This vial packaging format pairs a defined specification with practical manufacturing and consumer-use considerations. Final selection should follow formula testing, closure trials, decoration review, and line qualification. The 13/425 designation should be verified dimensionally because nominal finish names do not guarantee identical sealing behavior. Appropriate markets can include essential oils, fragrance samples, extracts, diagnostics, and laboratory products. This is where practical engineering and brand presentation need to agree.
