70L LCD Digital Overhead Stirrer

Engineered for precision mixing in chemical, pharmaceutical, and cosmetic laboratories, the OS70-Pro combines advanced brushless DC motor technology with intuitive LCD controls to deliver consistent results even with high-viscosity materials up to 100,000 mPa·s. Ideal for researchers seeking reliable performance and time-saving features.

•Patented "Top-Cross" Stirring Paddle– Unique design ensures uniform mixing and easy container replacement, reducing downtime between experiments. Compatible with glass reactors and stainless-steel vessels.

•Advanced LCD Interface– Real-time display of set/actual speed (50-1100 rpm), torque (up to 300N·cm), and timer (0-99h59min) allows precise process monitoring. Critical for reproducible results in R&D environments.

•Dual-Protection Safety System– Spillage-resistant housing and overload protection circuits prevent motor burnout during high-viscosity mixing. Meets IP21 standards for lab safety compliance.

•Maintenance-Free Brushless Motor– Delivers 160W output power with minimal noise (<55dB). Eliminates carbon brush replacement, reducing total cost of ownership by 40% compared to traditional motors.

•Tool-Free Chuck System– Self-locking drill chuck (0.5-10mm diameter range) enables quick paddle changes without additional tools. Perfect for multi-sample workflows.

•Smooth Start Technology– Gradual acceleration prevents sample splatter and overflow, protecting valuable reagents and improving operator safety.

•Constant Speed Under Viscosity Changes– Maintains set speed even as sample viscosity increases, ensuring consistent mixing in polymerization and emulsion processes.

•Chemical-Resistant Design– Silicone chuck cover protects internal components from corrosive vapors, extending equipment lifespan in harsh lab environments.
