Manufactured from high-quality 316 stainless steel with 7mm shaft diameter for universal compatibility with Achiever 5000 overhead stirrers, this versatile collection includes Floating Blade, Fixed Blade, Folding Blade, Turbine, Propeller, Turbo Propeller, Paddle (6 Holes), and Anchor configurations—each precisely designed to create specific flow patterns (radial, axial, or tangential) optimized for particular application requirements.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eShaft lengths range from 400mm to 510mm with blade dimensions from 45 × 54mm to 93 × 11mm, accommodating vessels from narrow-neck flasks to large beakers while handling viscosity ranges from 0 cP (water-like) to 100,000 cP (highly viscous pastes and gels). Speed capabilities span from gentle mixing at up to 800 RPM (Paddle) to high-speed operation at 250 RPM maximum (most radial and axial designs), with the versatile Anchor shaft supporting all speed ranges for maximum flexibility.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSelecting the appropriate stirring shaft requires consideration of five critical questions: sample type, sample viscosity, sample volume, speed range requirements, and mixing preference (homogenization, suspension, dispersion, emulsification, or gentle blending). Radial flow shafts (Floating Blade, Fixed Blade, Folding Blade, Turbine) create circular flow patterns from top to bottom ideal for narrow-neck vessels, vortex creation, and medium to high-speed applications with viscosities ranging from very low (0-100 cP) to high (10,000-100,000 cP). Axial flow shafts (Propeller, Turbo Propeller) generate top-to-bottom flow with limited shearing forces, excellent for homogenization and suspensions in medium to high viscosity materials (1,000-100,000 cP), with the Turbo Propeller featuring a protective ring to shield dip tubes and sensors from blade contact. Tangential flow shafts (Paddle 6 Holes, Anchor) produce reduced turbulence with high shearing forces concentrated at vessel walls, ideal for gentle mixing at low to medium speeds in medium to high viscosity materials (1,000-100,000 cP), with the Anchor design specifically preventing sedimentation on vessel walls in high-viscosity applications.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eCompatible with the complete Achiever 5000 overhead stirrer platform and backed by manufacturer warranty, these precision-engineered stirring shafts deliver reliable, repeatable mixing performance for laboratory research, quality control, production scale-up, and industrial process development applications requiring versatile, application-specific stirring solutions.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eFeatures of Ohaus Overhead Stirrer Shafts:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1 Year Warranty on all accessories: \u003c\/strong\u003eComprehensive Quality Assurance - Backed by manufacturer warranty with precision engineering and 316 stainless steel construction ensuring long-term reliability, chemical resistance, and consistent mixing performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEight Specialized Shaft Designs\u003c\/strong\u003e - Complete range includes Floating Blade, Fixed Blade, Folding Blade, Turbine, Propeller, Turbo Propeller, Paddle (6 Holes), and Anchor configurations for application-specific mixing optimization.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e316 Stainless Steel Construction\u003c\/strong\u003e - High-quality 316 stainless steel provides excellent chemical resistance, corrosion protection, autoclavability, and durability for demanding laboratory and industrial mixing applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal 7mm Shaft Diameter\u003c\/strong\u003e - Standard 7mm shaft diameter ensures compatibility across the complete Achiever 5000 overhead stirrer platform, enabling easy shaft interchange for different applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Viscosity Range Capability\u003c\/strong\u003e - Handles samples from 0 cP (water-like) to 100,000 cP (highly viscous pastes), with shaft designs optimized for very low, low, medium, and high viscosity materials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultiple Flow Pattern Options\u003c\/strong\u003e - Radial flow (circular top-to-bottom), axial flow (vertical with limited shear), and tangential flow (wall-focused with high shear) patterns accommodate diverse mixing requirements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Speed Range Compatibility\u003c\/strong\u003e - Speed capabilities from gentle mixing at up to 800 RPM (Paddle) to high-speed operation at 250 RPM maximum, with Anchor shaft supporting all speed ranges.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication-Specific Blade Geometries\u003c\/strong\u003e - Blade dimensions from 45 × 54mm to 93 × 11mm and lengths from 400mm to 510mm optimize mixing efficiency for narrow-neck vessels to large containers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecialized Protection Features\u003c\/strong\u003e - Turbo Propeller includes protective ring to shield dip tubes and sensors;
