Manufactured from optically clear, medical-grade polycarbonate, this flask features a triple-baffled bottom designed to maximize oxygen transfer by increasing turbulence and surface area during agitation. The included 43 mm vent cap incorporates a 0.2 µm hydrophobic membrane, allowing for continuous, sterile gas exchange while preventing contamination and liquid leakage. With its shatter-proof construction and molded-in graduations, the 431256 offers a safer and more efficient alternative to traditional glass vessels, making it the industry standard for protein expression, vaccine development, and scale-up studies in orbital shakers.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eTriple-Baffled Bottom:\u003c\/b\u003e The molded-in baffles disrupt laminar flow during shaking, significantly enhancing aeration and gas-liquid mass transfer, which is critical for the growth of oxygen-demanding microorganisms.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eHydrophobic Vent Cap:\u003c\/b\u003e The integrated 0.2 µm pore size membrane ensures a consistent supply of oxygen and CO2 while providing a reliable sterile barrier against airborne contaminants.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSuperior Mechanical Strength:\u003c\/b\u003e Constructed from high-impact polycarbonate, this flask is designed to withstand the physical stresses of high-speed orbital shaking without the risk of shattering associated with glass.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eOptical Clarity:\u003c\/b\u003e Glass-like transparency allows for easy visual monitoring of culture turbidity, color changes, and the presence of precipitates or contamination.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCatalog Number:\u003c\/b\u003e 431256\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCapacity:\u003c\/b\u003e 2 Liters (2000 ml)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eBase Style:\u003c\/b\u003e Baffled Bottom\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCap Style:\u003c\/b\u003e 43 mm Vent Cap (0.2 µm Membrane)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMaterial:\u003c\/b\u003e Polycarbonate (Flask); High-Density Polyethylene (Cap)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSterility:\u003c\/b\u003e Sterile (Gamma Irradiated to SAL 10^-6)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePurity:\u003c\/b\u003e Certified Non-Pyrogenic and Non-Cytotoxic.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eGraduations:\u003c\/b\u003e Molded-in at 200 ml increments.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eAerobic Fermentation:\u003c\/b\u003e Ideal for culturing E. coli, yeast, and other aerobic organisms that require high dissolved oxygen levels for optimal protein expression.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCell Culture Scale-Up:\u003c\/b\u003e Provides a reliable environment for transitioning suspension-adapted mammalian or insect cells from small-scale tubes to pilot production.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eAseptic Gas Exchange:\u003c\/b\u003e The vent cap eliminates the need to \"loosen\" caps for aeration, maintaining a completely closed, sterile system during incubation.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSingle-Use Convenience:\u003c\/b\u003e Delivered sterile and ready-to-use, eliminating the time and costs associated with washing, autoclaving, and validating reusable glassware.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\u003cp style=\"margin: 0; font-size: 0.8em;\"\u003e\u003ci\u003eAll product names, logos, and brands are property of their respective owners.\u003c\/i\u003e\u003c\/p\u003e","brand":"Corning","offers":[{"title":"Default Title","offer_id":44498004377852,"sku":"4097","price":114.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/corning-erlenmeyer-flask-2l-with-vent-cap-baffled-polycarbonate-case-of-6-flasks-lab-culture-flask-corning-800681.jpg?v=1766475022","url":"https:\/\/lifesciencestrading.com\/products\/corning-erlenmeyer-flask-2l-with-vent-cap-baffled-polycarbonate","provider":"Life Sciences Trading","version":"1.0","type":"link"}
