Digital Overhead Stirrer 40L for Professional Laboratory Mixing The digital overhead stirrer 40L delivers precise speed control and consistent mixing performance for research labs, chemical synthesis, and pharmaceutical applications requiring reliable batch processing. The Scilogex SCI40-S model combines advanced digital overhead stirrer technology with 60 Ncm high torque capability, making it ideal for laboratories that demand both precision and powerful mixing in a 40-liter capacity system. This 40L laboratory stirrer features a brushless DC motor, LED speed display, and comprehensive safety circuits designed for demanding industrial and research environments. High-Performance Digital Controls and Precision Monitoring The digital overhead stirrer 40L incorporates an LED display that monitors both set speed and actual speed in real-time, ensuring batch-to-batch consistency and repeatability. Speed adjustment ranges from 50 to 2,200 RPM with ±50 RPM accuracy, providing precise control for diverse mixing applications. The advanced digital overhead stirrer automatically resumes preset speed after power loss, enabling uninterrupted overnight operations critical for chemical synthesis and pharmaceutical manufacturing. Over-torque protection automatically stops the motor if resistance exceeds safe operating parameters, protecting equipment and operator safety. High-Torque Capacity for Viscous Mixing Applications This 40L laboratory stirrer delivers 60 Newton-centimeters (Ncm) of maximum torque, enabling smooth rotation even when processing highly viscous solutions up to 50,000 millipascals (mPas). The powerful digital overhead stirrer 40L maintains constant speed even as fluid viscosity changes during mixing, essential for emulsions, suspensions, and complex chemical reactions requiring stable torque delivery. The brushless DC motor provides long-term reliability without routine maintenance, reducing laboratory downtime and operational costs associated with worn brushes or motor repairs. Key Technical Specifications: Capacity: 40 liters (H2O maximum) Speed Range: 50 to 2,200 RPM with ±50 RPM accuracy Maximum Torque: 60 Ncm (85 ounce-inches) Maximum Viscosity: 50,000 mPas (millipascals) at 2,200 RPM Display: LED digital display showing set and actual speeds Motor Type: Maintenance-free brushless DC motor Motor Input/Output: 120W input, 100W output Chuck Diameter Range: 0.5 to 10 millimeters Protection: IP42 rating, overload protection, over-temperature protection Dimensions: 3.3" W × 7.3" D × 8.7" H (83 × 186 × 220 mm) Weight: 5.5 pounds (2.5 kilograms) Power Supply: Universal 100-220V AC, 50/60 Hz, 130W Certifications: cTUVus approved for UL and CSA compliance Through-Shaft Design for Laboratory Flexibility The digital overhead stirrer 40L features a through-shaft design allowing easy adjustment of impeller position without complete equipment repositioning. Pass-through stirrer rods accommodate various shaft diameters and impeller configurations, providing flexibility for different mixing scenarios. This laboratory stirrer accepts both standard and custom stirring impellers, enabling researchers to optimize mixing performance for specific applications from dissolving solids to creating emulsions and suspensions. Advanced Safety Circuits and Overload Protection The digital overhead stirrer 40L incorporates multiple safety circuits that automatically engage during anti-stall conditions or motor overload situations, preventing equipment damage and operator injury. The LED display provides immediate visual feedback on overload conditions, allowing laboratory personnel to quickly identify problems and adjust mixing parameters. Comprehensive protection includes motor protection circuits, over-temperature protection, and overload detection systems that ensure safe operation even during challenging high-viscosity mixing or accidental impeller contact. Durable Construction for Demanding Laboratory Environments Built with stainless steel components and precision engineering, this digital overhead stirrer 40L withstands the demanding conditions of active research laboratories and chemical production facilities. The SCI40-S model maintains dimensional stability and precise performance across thousands of mixing cycles, supporting long-term laboratory operations. The included stainless steel cross-stirrer shaft (part #1890007) provides chemically resistant mixing capability compatible with wide-ranging solvent systems and reactive chemical compounds common in pharmaceutical, polymer, and cosmetic research. Professional-Grade Reliability with Extended Warranty Every digital overhead stirrer 40L includes a comprehensive two-year manufacturer's warranty covering equipment failure and component defects. Scilogex's factory-backed warranty ensures rapid replacement or repair response, minimizing laboratory disruptions during critical research phases. The SCI40-S model has earned trust across research institutions, educational facilities, pharmaceutical manufacturers, and industrial laboratories worldwide for its consistent performance, reliability, and cost-effective operation compared to premium-priced alternatives.
