Serile Rubber Stopper A 13mm
$3.00
Ensure sterile, leak-proof containment for liquid injectables with the 13mm Sterile Injection Rubber Stopper (13-A) from vialshop.com. Engineered for standard 13mm neck glass serum and injection vials (7mm internal diameter), this medical-grade butyl rubber stopper features a classic flat plug design with exceptional self-healing properties. Pre-sterilized and chemically inert, it allows repeated needle punctures without coring or fragmenting—making it ideal for vaccines, parenteral drugs, and liquid culture media.
The 13mm Sterile Injection Rubber Stopper (Model 13-A) from vialshop.com provides robust, high-integrity sealing for liquid injectables, serum vials, and diagnostic solutions. Formulated from premium bromobutyl or chlorobutyl elastomer, this stopper is engineered to deliver zero leachables, ultra-low gas permeability, and high resistance to chemical degradation.
Designed specifically for standard 13mm ISO-finish injection vials, the 13-A model provides an airtight, hermetic compression fit under aluminum flip-off or tear-off crimp seals. Its optimized elastomer elasticity ensures smooth needle penetration and instant self-healing upon withdrawal, protecting liquid contents against airborne contamination and vacuum loss.
