LED Overhead Stirrer

The LED Overhead Stirrer is a high-capacity LED digital overhead mechanical stirrer featuring a brushless DC motor (120W input / 100W output), microprocessor-controlled speed regulation (50-2200 rpm, accuracy ±3 rpm), LED display for real-time speed monitoring, enhanced torque (60 N·cm), and increased viscosity handling (up to 50,000 mPa·s), designed for demanding high-viscosity and large-volume (up to 40 liters) mixing, homogenizing, and suspending applications in clinical diagnostic, pharmaceutical, and research laboratories .

Key features include a maintenance-free, explosion-proof brushless DC motor for quiet, long-lasting operation and safe use in volatile environments; through-shaft design for easy impeller height adjustment; anti-spill slow-start mechanism to prevent sample splashing; overload protection (LED indicator lights, motor automatic stop in case of continuous overload) for equipment and sample safety; and compatibility with a wide range of stirrer shafts (0.5-10 mm chuck diameter) .

The  LED Overhead Stirrer represents a significant upgrade from the LED Overhead Stirrer, with double the stirring capacity (40L vs 20L), double the output power (100W vs 50W), 50% higher torque (60 N·cm vs 40 N·cm), and five times higher viscosity handling (50,000 mPa·s vs 10,000 mPa·s), making it suitable for the most demanding high-viscosity applications .

For the pharmaceutical formulation scientist and quality control chemist, the  LED Overhead Stirrer supports mixing of high-viscosity creams, ointments, gels, and suspensions at batch sizes up to 40L, API dissolution testing, and large-volume buffer and media preparation . For the biopharmaceutical manufacturing scientist, it enables processing of cell pastes, protein solutions, and fermentation broths with viscosity up to 50,000 mPa·s . For the clinical laboratory scientist, it facilitates bulk reagent preparation for high-volume immunoassays and clinical chemistry analyzers .

Universal voltage (100-240V, 50/60Hz) enables use in laboratories worldwide without voltage conversion, while the compact (83 × 220 × 186 mm) and lightweight (2.8 kg) design allows easy benchtop placement . The IP42-rated splash-resistant housing ensures safe operation in biosafety cabinets and fume hoods, including handling of biohazardous materials .

For the patient undergoing pharmaceutical therapy, the  LED Overhead Stirrer enhanced torque and viscosity handling ensure consistent formulation quality, batch-to-batch uniformity, and accurate API release testing—supporting the manufacturing of safe, effective high-viscosity medications such as topical creams, ointments, and biopharmaceuticals . For patients requiring diagnostic testing, consistent large-volume reagent preparation reduces inter-run variability and improves the reliability of diagnostic test results across high-volume clinical chemistry, pharmaceutical QC, and analytical testing applications .
