Ohaus Achiever 5000 Overhead Stirrer Shafts

Ohaus Achiever 5000 Overhead Stirrer Shafts

The Ohaus stirring shafts for Achiever 5000 series overhead stirrer represent a comprehensive range of eight specialized stirring shaft designs engineered to optimize mixing performance across diverse sample types, viscosities, volumes, speed ranges, and mixing preferences. 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.

Shaft 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.

Selecting 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.

Compatible 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.

Applications for Ohaus Overhead Stirrer Shafts:

• Chemical Synthesis and Reaction Monitoring: Radial flow shafts (Fixed Blade, Turbine) create vortex mixing for chemical reactions requiring high shear, rapid homogenization, and efficient heat transfer in round-bottom flasks.
• Pharmaceutical Formulation Development: Axial flow shafts (Propeller, Turbo Propeller) provide gentle, consistent mixing for drug suspensions, emulsions, and formulations requiring homogenization without excessive shearing of active ingredients.
• High-Viscosity Polymer and Resin Mixing: Anchor shaft with tangential flow prevents wall sedimentation and provides high shearing forces for mixing viscous polymers, resins, adhesives, and gels (10,000–100,000 cP).
• Emulsion Preparation and Stabilization: Turbine shaft creates high shear and turbulence for breaking down agglomerations, dispersing immiscible liquids, and producing stable emulsions in cosmetic and food applications.
• Suspension Maintenance and Particle Distribution: Propeller shaft generates axial flow with limited shearing for maintaining uniform particle suspensions in paints, coatings, slurries, and particulate-containing formulations.
• Quality Control and Laboratory Testing: Folding Blade design accommodates narrow-neck vessels and volumetric flasks for quality control testing, while the complete shaft range supports method development and analytical procedures across diverse viscosity ranges.
