Unlike standard benchtop impellers, this heavy-duty version features a 15 mm inner bore designed to mount onto high-torque pilot-scale stirrer shafts. This impeller is the industry standard for microbial fermentation where high oxygen mass transfer (kLa) and intensive gas dispersion are required. Fabricated from medical-grade AISI 316L stainless steel and finished to exacting pharmaceutical standards, it provides the ruggedness and precision needed for validated pilot-scale bioprocessing.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePilot-Scale Power:\u003c\/b\u003e Designed specifically for the increased torque requirements of 10 L to 15 L stainless steel vessels, ensuring stable agitation even in high-viscosity microbial broths.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSuperior Gas Breakup:\u003c\/b\u003e The Rushton-style disk intercepting the gas stream at the sparger creates high shear zones, effectively reducing bubble size and maximizing dissolved oxygen (DO) levels.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003e15 mm Precision Bore:\u003c\/b\u003e Machined for a zero-tolerance fit on 15 mm diameter shafts, preventing shaft wear and mechanical vibration during high-speed fermentation runs.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003e316L Stainless Steel:\u003c\/b\u003e Constructed from electropolished, low-carbon stainless steel (Ra \u0026lt; 0.4 µm) to withstand aggressive SIP steam cycles and prevent microbial hiding spots.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCatalog Number:\u003c\/b\u003e BB-8843940\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eImpeller Type:\u003c\/b\u003e 6-Blade Disk (Rushton Turbine)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eDiameter:\u003c\/b\u003e 75 mm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eBore Diameter:\u003c\/b\u003e 15 mm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSystem Compatibility:\u003c\/b\u003e Sartorius Biostat® Cplus (10 L \/ 15 L), D-DCU Series.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMaterial:\u003c\/b\u003e AISI 316L Stainless Steel\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eValidated Process Scale-Up:\u003c\/b\u003e Essential for laboratories moving from benchtop R\u0026amp;D to pilot-scale production, ensuring the mixing profile remains consistent with the larger 30 L and 50 L SIP systems.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eExtreme Durability:\u003c\/b\u003e The thicker hub and reinforced blade welds are designed for the high-pressure environments of Sterilize-In-Place (SIP) operations.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eOxygen-Hungry Cultures:\u003c\/b\u003e The primary tool for E. coli, P. pastoris, and other high-density microbial cultures requiring rapid gas exchange.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\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":"Sartorius","offers":[{"title":"Default Title","offer_id":49003826446588,"sku":"10668","price":675.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/sartorius-bioreactor-disk-impeller-6-blade-15mm-inner-bore-for-10l-15l-vessel-lab-equipmentbioreactors-fermenters-sartorius-318308.jpg?v=1776639610","url":"https:\/\/lifesciencestrading.com\/zh\/products\/sartorius-bioreactor-disk-impeller-6-blade-for-10l-vessel","provider":"Life Sciences Trading","version":"1.0","type":"link"}
