Digital Overhead Stirrer

The Pro Overhead Stirrer is a digital overhead mechanical stirrer featuring a brushless DC motor (60W input / 50W output), microprocessor-controlled speed regulation (50-2200 rpm), LCD display for real-time monitoring of speed and torque, RS232 interface for PC control and data logging, and IP42 splash-resistant protection, designed for high-viscosity (up to 10,000 mPa·s) and large-volume (up to 20 liters) mixing, homogenizing, and suspending applications in clinical diagnostic, pharmaceutical, and research laboratories.

Key features include a maintenance-free brushless DC motor for quiet, long-lasting operation, through-shaft design for easy impeller height adjustment, automatic torque adjustment based on sample viscosity, over-torque protection (automatic motor stop to prevent damage), anti-spill slow-start mechanism, and compatibility with a wide range of stirrer shafts (0.5-10 mm chuck diameter).

For the pharmaceutical formulation scientist and quality control chemist, the Pro Overhead Stirrer supports mixing of creams, ointments, gels, and suspensions, API dissolution testing, and large-volume buffer and media preparation. For the analytical chemist, it enables pH titration and reaction monitoring with PC control and data logging (RS232). For the clinical laboratory scientist, it facilitates bulk reagent preparation for 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.

For the patient undergoing pharmaceutical therapy, the Pro Overhead Stirrer precise speed control and torque monitoring ensure consistent formulation quality, batch-to-batch uniformity, and accurate API release testing—supporting the manufacturing of safe, effective medications. For patients requiring diagnostic testing, consistent reagent preparation across large batches reduces inter-run variability and improves the reliability of diagnostic test results across clinical chemistry, pharmaceutical QC, and analytical testing applications.
