Foxx Erlenmeyer Flask 2 L EZClear Versacap 53B Case of 6 Flasks

Description

Foxx Life Sciences EZclear Erlenmeyer Shaker Flask – 2 L, Flat Base, Polycarbonate, Sterile, 53B Vented Versacap (MPN: 248-5132-OEM)

The Foxx Life Sciences 248-5132-OEM is a premium, sterile 2-liter Erlenmeyer shaker flask engineered for mammalian cell culture, microbial fermentation, media preparation, and general fluid scaling. Molded from USP Class VI, virgin, optically clear polycarbonate (PC) resin in a Class 100,000 cleanroom, this heavy-duty vessel features a completely flat base that maximizes stability on mechanical incubator shaker platforms. It comes equipped with a patented 53B (53 mm) Polypropylene Versacap® configuration featuring an integrated 0.2 µm hydrophobic PTFE membrane. This combination permits safe, high-velocity gas exchange and equilibrial oxygenation while blocking external biological pollutants and aerosol carryover.

Technical Performance and Design

• Virgin Polycarbonate Optical Clarity: Fabricated from high-grade, non-leaching polycarbonate that exhibits extreme impact resistance and structural stability, maintaining pristine glass-like transparency even after undergoing high-dosage gamma sterilization treatments.

• Patented 53B Vented Versacap® Technology: The large-diameter 53 mm cap includes a high-surface-area 0.2 µm hydrophobic PTFE filter. This matrix facilitates continuous, uniform aerobic gas exchange across the headspace to minimize internal pH shifts and sample oxidation.

• Universal Shaking Deck Compatibility: Features a classic wide-base Erlenmeyer silhouette designed to drop directly into all industry-standard benchtop and floor-model shaking incubator clamps, sticky pads, or dedicated multi-flask platform racks.

• Molded-In Volumetric Graduations: Precision-imprinted with clear, high-accuracy structural fluid markers running down the exterior body, allowing for rapid visual validation of current culture parameters without opening the sterile seal.

Key Benefits & Applications

• Suspension Mammalian Culture: Highly optimized for growing suspension lines, primary antibody production, and transient transfections inside large-scale CO₂ shaking incubator chambers.

• Microbial & Yeast Fermentation: The flat-base profile provides predictable fluid dynamics for low-to-medium shear microbial expansions and pilot scale seed-train development.

• Autoclavable Reusability: Engineered to withstand standard thermal sanitization protocols ($121^circtext{C}$ / 250°F at 15 PSI for 20 minutes), allowing laboratories to repeatedly wash and re-sterilize the flask housing when required.

• Biologics Liquid Archiving: Complying with strict FDA food-contact and USP extraction rules, it is widely utilized for storing sensitive downstream biopharma buffers, down-stream media feeds, and active bulk intermediates.
