Wheaton Serum Vial 50 ml Glass 43 x 73mm 20mm Mouth OD 72 Vials

WHEATON 223745 Serum Bottle – 50 mL, Clear, USP Type I Borosilicate Glass

The WHEATON 223745 (distributed by DWK Life Sciences) is a premium 50 mL clear glass serum bottle engineered for the secure containment, long-term storage, and lyophilization of critical biological samples, vaccines, and injectable drugs. Molded from high-purity WHEATON 400 low-alkali borosilicate glass, it conforms strictly to USP Type I requirements. This robust formulation ensures exceptional chemical tolerance, high thermal shock resistance, and complete gas impermeability. Featuring a standard 20 mm crimp-neck finish with a 13 mm internal opening, this autoclavable bottle is designed to provide an absolute hermetic seal when paired with standard rubber stoppers and aluminum crimp caps.

Technical Performance and Design

• USP Type I Borosilicate Glass: The clear, low-alkali molded glass matrix provides maximal resistance to chemical leaching and hydrolytic attack, safely preserving the stability of sensitive alkaline or acidic reagents.

• Exceptional Wall Strength: Optimized for freeze-drying (lyophilization) protocols, the reinforced, uniform wall geometry safely handles the intense negative pressures and radical temperature swings of the sublimation process.

• Standardized Crimp Finish: Features a 20 mm outer diameter (OD) neck finish. The flat, uniform rim guarantees a secure, uncompromised seal with 20 mm aluminum crimp closures, preventing sample evaporation or atmospheric ingress.

• Shrink-Wrapped Partitioned Packaging: Factory-packed in specialized partitioned modules that prevent glass-on-glass friction, minimizing ambient particle contamination and eliminating shipping breakage.

Key Benefits & Applications

• Pharmaceutical & Vaccine Containment: The industry-standard vessel for packaging active pharmaceutical ingredients (APIs), diagnostic therapeutics, and liquid vaccine components.

• Lyophilization (Freeze-Drying): The structural resilience of the glass prevents cracking during ultra-low temperature shelf freezing and subsequent vacuum pulls.

• Gas-Impermeable Archiving: Ideal for oxygen-sensitive compound storage where standard plastic vials risk atmospheric gas permeation or volatile extraction solvent loss.

• Contamination-Free Workflow: Arrives free of organic extractables or heavy metal contaminants, making it a reliable standard for trace-analytical sample collection and media preparation.
