Serile Rubber Stopper D1 13mm

$3.00

Protect small-volume freeze-dried samples with the 13mm Sterile Lyophilization Rubber Stopper (13-D1) from vialshop.com. Specifically engineered for 13mm neck tubular and molded glass injection vials, this pharmaceutical-grade butyl rubber stopper features a specialized single-vent (single-leg) design to facilitate efficient vapor escape during lyophilization. Pre-sterilized and chemically inert, it ensures low moisture absorption, high thermal stability, and an airtight, contamination-free seal for sensitive powders, diagnostic reagents, and injectable pharmaceuticals.

The 13mm Sterile Lyophilization Rubber Stopper (Model 13-D1) from vialshop.com offers reliable, high-integrity sealing for freeze-drying applications in small-dose vials. Formulated from high-purity bromobutyl/chlorobutyl rubber, this stopper provides maximum chemical stability, low gas permeability, and minimal leachables.

Its single-leg (D1 single-vent) profile allows the stopper to sit securely in the partially inserted position during freeze-drying, giving moisture vapor an unobstructed path to escape during sublimation. Once the vacuum freeze-drying cycle completes and the stoppering mechanism seals the vial, it creates a tight, hermetic barrier that protects delicate biological products, APIs, and freeze-dried formulations from atmospheric humidity and oxygen.

Key Features

Single-Leg Vented Design (13-D1): Engineered for stability in the half-stoppered position, allowing efficient vapor sublimation prior to final mechanical seating.
Pharmaceutical-Grade Butyl Rubber: High-purity formulation provides excellent chemical resistance, low moisture transmission, and low extraction levels.
Pre-Sterilized & Cleanroom Ready: Processed under strict YBB, EP, and ISO standards for immediate use in aseptic filling lines.
13mm Neck Finish: Fits standard 13mm outer diameter glass injection vials, freeze-drying bottles, and serum vials (7mm internal neck diameter).
Hermetic Vacuum Retention: Elasticity and integrity remain uncompromised through extreme freezing and heating cycles, guaranteeing a long-term vacuum seal under aluminum crimp caps.
