Rubber Stoppers
Quick answer: Morgan Chemicals supplies Rubber Stoppers across Pakistan as part of its Closures & Components range, with quotations available via info@morgan.pk.
Bromobutyl, chlorobutyl and fluoropolymer-coated rubber stoppers for injection vials, cartridges and lyophilized biologics — engineered for low extractables, low moisture vapour transmission and full container closure integrity.
What are Rubber Stoppers?
The rubber stopper is the most critical closure component in any parenteral container. It must provide a microbial barrier, withstand reseal after needle penetration, and contribute negligible extractables and leachables to the drug product. Material chemistry is selected per drug compatibility.
Key Features & Technical Specifications
- Bromobutyl rubber — low MVTR, excellent chemical resistance for lyophilized biologics
- Chlorobutyl rubber — lower cost, excellent for aqueous injectables
- Fluoropolymer-coated (Teflon® / ETFE) — ultra-low extractables for biologics and high-value APIs
- Lyo, serum and infusion stopper geometries
- Ready-to-Sterilise (RtS) and Ready-to-Use (RtU) supply formats
Applications
- Lyophilized biologics and vaccines
- Aqueous injectables (antibiotics, analgesics)
- High-value monoclonal antibodies
- Cytotoxic and oncology injectables
- Cartridge and prefilled syringe plungers
Materials & Grades
- Bromobutyl rubber (most common for biologics)
- Chlorobutyl rubber (cost-effective aqueous)
- Fluoropolymer-coated bromobutyl (premium biologics)
