Manufactured from medical-grade, high-clarity polypropylene, these 250 ml tubes offer the chemical resistance and structural integrity required for demanding laboratory applications. Featuring a specialized HDPE Plug Seal Cap, these tubes provide a reliable, leak-proof barrier even during high-speed centrifugation. Each tube is gamma-irradiated to ensure sterility and is certified non-pyrogenic, making them ideal for biopharmaceutical production and sensitive biological research.\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\u003eHigh-Capacity Processing:\u003c\/b\u003e The 250 ml volume is optimized for large-scale cell harvesting, pelleting, and protein purification workflows that exceed the capacity of standard 50 ml conical tubes.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePlug Seal Cap Technology:\u003c\/b\u003e The high-density polyethylene (HDPE) cap is designed with a deep-seated plug that creates a multi-point friction seal against the inner wall of the tube, ensuring a liquid-tight and gas-tight closure.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSuperior Chemical Resistance:\u003c\/b\u003e Polypropylene construction provides excellent compatibility with a wide range of laboratory solvents, alcohols, and acids, and allows for use in cold storage or heated water baths.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePrecision Molded Graduation:\u003c\/b\u003e Features easy-to-read, molded-in graduations to facilitate accurate volume measurement and sample tracking during large-scale liquid handling.\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 430776\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCapacity:\u003c\/b\u003e 250 ml\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMaterial:\u003c\/b\u003e Polypropylene (Tube) \/ HDPE (Cap)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMax RCF:\u003c\/b\u003e 6,000 x g (Note: Must be used with appropriate rotor cushions\/adapters)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSterility:\u003c\/b\u003e Sterile (Gamma Irradiated); Non-pyrogenic\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePackaging:\u003c\/b\u003e 6 Tubes per Bag \/ 102 Tubes per Case\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eDimensions:\u003c\/b\u003e Approx. 60 mm (OD) x 158 mm (Length)\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\u003eBioprocessing \u0026amp; Scale-Up:\u003c\/b\u003e Ideal for harvesting cells from large-scale fermenters or bioreactors and for the initial stages of downstream processing.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eLarge Volume Storage:\u003c\/b\u003e The sterile, leak-proof design makes these tubes excellent for storing bulk buffers, media, or chemical reagents in a stable, upright format.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eReliable Durability:\u003c\/b\u003e Engineered with thick-walled construction to withstand the mechanical stresses of high-speed centrifugation without cracking or leaking.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eVerified Purity:\u003c\/b\u003e Certified to be free of DNase, RNase, and endotoxins, ensuring the integrity of sensitive genomic and proteomic samples.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eUsage Requirement\u003c\/h3\u003e\n\u003cp\u003eTo ensure safety and performance, these 250 ml tubes must be used with appropriate centrifuge rotor cushions or adapters (e.g., Corning 430236) to prevent tube failure during operation at maximum RCF.\u003c\/p\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":44494176747772,"sku":"1285","price":144.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/corning-430776-centrifuge-tubes-250-ml-plug-seal-cap-sterile-case-of-102-centrifuge-tubes-corning-527558.jpg?v=1778281711","url":"https:\/\/lifesciencestrading.com\/products\/corning-centrifuge-tubes-250-ml-plug-seal-cap-sterile","provider":"Life Sciences Trading","version":"1.0","type":"link"}
