Plus Overhead Stirrer

The Plus Overhead Stirrer is a high-torque LCD digital timed overhead stirrer featuring a brushless DC motor (120W input / 100W output), microprocessor-controlled speed regulation (50-2200 rpm), large LCD display for real-time monitoring of set speed, actual speed, torque trend, timer, and temperature (with optional PT1000 probe), forward/reverse/intermittent mixing modes, RS485/Type-C/USB data interfaces for PC control and data logging, and programmable timer (1 minute to 99 hours 59 minutes), designed for high-viscosity (up to 50,000 mPa·s) and large-volume (up to 50 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; constant speed technology that automatically adjusts torque according to sample viscosity changes to maintain set speed ; through-shaft design for easy impeller height adjustment and easy container replacement ; PT1000 temperature sensor port for real-time sample temperature monitoring (accuracy ±0.2°C, display 0.1°C) ; forward, reverse, and intermittent mixing modes for optimized stirring ; programmable timer (1 min-99h59min) with audible alert for unattended overnight operation ; safety lock to prevent accidental setting changes ; IP42 splash-resistant rating; multiple data interfaces (RS485, Type-C, USB) for PC control and LIMS integration ; torque and temperature calibration options for reproducible measurements ; and integrated power supply (no external transformer) for enhanced safety .

For the pharmaceutical formulation scientist and quality control chemist, the OS-T60-Plus supports mixing of high-viscosity creams, ointments, gels, and suspensions at batch sizes up to 50L, API dissolution testing, and large-volume buffer and media preparation . For the biopharmaceutical manufacturing scientist, it enables processing of cell pastes, protein solutions, fermentation broths, and monoclonal antibody formulations with viscosity up to 50,000 mPa·s . For the clinical laboratory scientist and diagnostic manufacturing manager, it facilitates industrial-scale bulk reagent preparation for high-volume immunoassays, clinical chemistry analyzers, and diagnostic kit manufacturing .

Universal voltage (100-240V, 50/60Hz) enables use in laboratories worldwide without voltage conversion, while the compact (90 × 240 × 227 mm) and lightweight (3.5 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 . RS485, Type-C, and USB connectivity allow integration into automated workflows and LIMS for GLP/GMP documentation .

For the patient undergoing pharmaceutical therapy, the OS-T60-Plus's precise speed control, constant speed technology, and torque monitoring 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, transdermal patches, and biopharmaceuticals . For patients requiring diagnostic testing, consistent industrial-scale 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 .
