Corning Cellbind Cell Culture Flask 175 cm2 U Shaped with Vent Cap Case of 50 Flasks

Corning CellBIND 175 cm2 U-Shaped Cell Culture Flasks with Vent Cap, Sterile (3292) – Case of 50

The Corning CellBIND 175 cm2 U-Shaped Cell Culture Flasks (3292) are premium, high-yield biological vessels engineered to enhance cell attachment, expansion, and harvesting in demanding tissue culture protocols. Precision-molded from crystal-grade virgin polystyrene, these flasks feature Corning's proprietary CellBIND surface treatment—a patented microwave plasma process that incorporates higher oxygen content into the polystyrene surface matrix. This results in a significantly more hydrophilic growth area that improves cell attachment, accelerates spreading, and boosts cell yields under serum-reduced or serum-free media conditions. Designed with an ergonomic U-shaped body and an angled neck, these flasks facilitate smooth liquid pouring, extended pipette access, and efficient cell scraping. Supplied as a case of 50 sterile flasks (packaged in 10 inner bags containing 5 flasks each), this product line delivers certified contamination-free consistency for scale-up and bio-manufacturing applications.

Technical Performance & Structural Design

• Corning CellBIND Surface Modification: Incorporates additional oxygen into the polymer matrix via a specialized microwave plasma treatment, producing a durable, hydrophilic surface that promotes fast cell attachment and higher cell yields without protein coatings.
• Ergonomic U-Shaped Geometry: Features rounded shoulders and a contoured profile that eliminates dead corners, facilitates easier handling, and provides complete pipette and cell scraper access to the entire growth surface.
• 0.2 µm Hydrophobic Membrane Vented Cap: Outfitted with a breathable polytetrafluoroethylene (PTFE) filter cap that enables continuous, sterile air exchange in CO2 incubators while forming a liquid barrier against contamination.
• Angled Neck Profile: Built with an elevated, angled neck that minimizes liquid splash near the cap and simplifies pipetting when working inside biosafety cabinets.
• Optically Clear Virgin Polystyrene: Manufactured to strict distortion-free standards for clear visual inspection under phase-contrast microscopy.

Key Benefits & Applications

• Serum-Reduced & Primary Cell Culture: Enhances attachment and growth of fastidious cell lines, primary cells, stem cells, and cultures grown in low-serum or serum-free conditions.
• Scalable Cell Expansion: Serves as an ideal vessel for scaling up cell populations from smaller 25 cm2 or 75 cm2 flasks prior to seeding into roller bottles or bioreactors.
• Economic Alternative to Biological Coatings: Replaces costly and heat-unstable protein coatings (e.g., collagen or poly-L-lysine) with a permanent, room-temperature stable surface treatment.
• Aseptic Gas Exchange in CO2 Incubators: The integrated 0.2 µm membrane cap ensures optimal pH equilibrium without requiring manual cap loosening, maintaining strict contamination control.
