This model features a plain (flat) bottom design, which provides optimal fluid dynamics for sensitive suspension cultures that require lower shear forces. Manufactured from optically clear, shatterproof polycarbonate, this flask offers a safer and more durable alternative to glass for use in orbital shakers. The wide-mouth design facilitates easy filling and pipetting, while the integrated 0.2 micron hydrophobic vent cap ensures continuous, sterile gas exchange while maintaining a secure seal against contaminants and leakage.\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\u003ePlain (Flat) Bottom Design:\u003c\/b\u003e Provides a smooth surface for uniform mixing at lower speeds, making it ideal for shear-sensitive mammalian cell lines and general media storage.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003e0.2 µm Hydrophobic Vent Cap:\u003c\/b\u003e The breathable polypropylene cap contains a high-efficiency membrane that allows for optimal CO2 and O2 exchange while preventing microbial ingress and liquid leakage.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eHigh-Clarity Polycarbonate:\u003c\/b\u003e Provides the optical transparency of glass with superior mechanical strength, allowing for easy visual monitoring of culture density and media color changes.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSterile \u0026amp; Non-Pyrogenic:\u003c\/b\u003e Supplied gamma-irradiated (SAL 10⁻⁶) and certified non-pyrogenic, ensuring the flask is ready for immediate use in sensitive bioprocessing workflows.\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 431145\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCapacity:\u003c\/b\u003e 500 mL\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eBottom Style:\u003c\/b\u003e Plain \/ Flat Bottom\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eNeck Style:\u003c\/b\u003e Wide Mouth\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMaterial:\u003c\/b\u003e Polycarbonate (USP Class VI)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCap Type:\u003c\/b\u003e Vent Cap (0.2 µm Membrane)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSterility:\u003c\/b\u003e Sterile (Gamma Irradiated)\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\u003eMammalian Cell Culture:\u003c\/b\u003e The industry-standard vessel for the expansion of CHO, HEK293, and other suspension cell lines where steady, controlled aeration is required.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMedia Preparation \u0026amp; Storage:\u003c\/b\u003e The robust construction and breathable cap make it excellent for preparing, transporting, and storing sterile culture media and buffers.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eShatterproof Safety:\u003c\/b\u003e Eliminates the safety hazards associated with glass breakage in high-traffic laboratories or within mechanical shaking incubators.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSingle-Use Efficiency:\u003c\/b\u003e Eliminates the labor-intensive cleaning and sterilization validation associated with reusable glassware, reducing the risk of batch-to-batch carryover.\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":44497040965884,"sku":"3844","price":110.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/corning-erlenmeyer-flask-500-ml-with-vent-cap-pc-case-of-25-flasks-lab-culture-flask-corning-422356.jpg?v=1778281829","url":"https:\/\/lifesciencestrading.com\/products\/corning-erlenmeyer-flask-500-ml-with-vent-cap-pc","provider":"Life Sciences Trading","version":"1.0","type":"link"}
