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.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Structural Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCorning 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.\u003c\/li\u003e\n\u003cli\u003eErgonomic 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.\u003c\/li\u003e\n\u003cli\u003e0.2 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.\u003c\/li\u003e\n\u003cli\u003eAngled Neck Profile: Built with an elevated, angled neck that minimizes liquid splash near the cap and simplifies pipetting when working inside biosafety cabinets.\u003c\/li\u003e\n\u003cli\u003eOptically Clear Virgin Polystyrene: Manufactured to strict distortion-free standards for clear visual inspection under phase-contrast microscopy.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCatalog Number \/ MPN: 3292\u003c\/li\u003e\n\u003cli\u003ePrimary Manufacturer: Corning Life Sciences\u003c\/li\u003e\n\u003cli\u003eGrowth Surface Area: 175 cm2\u003c\/li\u003e\n\u003cli\u003eBody Shape \u0026amp; Neck Style: U-Shaped Body with Angled \/ Canted Neck\u003c\/li\u003e\n\u003cli\u003eCap Style Profile: Orange Vented Cap with 0.2 µm Hydrophobic Membrane\u003c\/li\u003e\n\u003cli\u003eMaterial Composition: Optical-Grade Virgin Polystyrene (PS Body) | High-Density Polyethylene (HDPE Cap)\u003c\/li\u003e\n\u003cli\u003eSurface Treatment Status: Corning CellBIND Surface Treatment (Enhanced Hydrophilic Attachment)\u003c\/li\u003e\n\u003cli\u003eSterility Certification: Pre-Sterilized via Gamma Irradiation (SAL 10-6)\u003c\/li\u003e\n\u003cli\u003ePurity Profile: Certified non-pyrogenic, non-cytotoxic, and free of detectable RNase and DNase contamination\u003c\/li\u003e\n\u003cli\u003eRecommended Working Volume: 35 mL to 52.5 mL (Maximum Volumetric Capacity: 650 mL)\u003c\/li\u003e\n\u003cli\u003ePackaging Configuration: Case of 50 flasks (10 inner sterile bags x 5 flasks per bag)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSerum-Reduced \u0026amp; 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.\u003c\/li\u003e\n\u003cli\u003eScalable 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.\u003c\/li\u003e\n\u003cli\u003eEconomic 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.\u003c\/li\u003e\n\u003cli\u003eAseptic 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.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eExpiration Date 2027-01-11\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003csmall\u003eAll product names, logos, and brands are property of their respective owners.
