Stoppers, Seals & Closures

Closure components that match our vials and bottles: bromobutyl and chlorobutyl rubber stoppers in serum, lyophilization and injection grades (13 mm and 20 mm), flip-off aluminum crimp seals in custom colors, child-resistant prescription bottle caps, bottle adapters and orifice reducers, and tamper-evident bands and induction seals. Buy components alone or as matched vial + stopper + seal systems.
