1/3 DRAM Screw Thread Clear Glass Vial 13/425

The 13/425 designation should be verified dimensionally because nominal finish names do not guarantee identical sealing behavior. The commercial value of this vial packaging format depends on disciplined component integration. Its application range extends to essential oils, fragrance samples, extracts, diagnostics, and laboratory products. Commercial approval should reflect filled-package testing under realistic processing and distribution conditions. This is where practical engineering and brand presentation need to agree.
