ECS-KM Benchtop Automatic Batch Reactor (Max. 10 MPa, 300°C, 1 L) with Mechanical Shaft Stirring, EKMBABRMSS

A benchtop automatic batch reactor with mechanical shaft stirring is the cornerstone equipment for process chemistry optimization, scale-up modeling, and precise kinetic control (e.g., polymerizations, slurry syntheses, crystallization, and controlled dosing reactions). Unlike simple magnetic stirrers, overhead mechanical shaft drives provide high torque to handle viscous reaction media, phase-transfer slurries, and precise, non-slip speed regulation across 50 to 2000 RPM.

The benchtop automated reactors integrate real-time sensor feedback with programmable logic controllers (PLCs) or PC software: (1) Closed-Loop Temperature Control: Cascaded PID loops monitor both internal bed/reaction temperature and jacket fluid temperature, dynamically adjusting heating/cooling circulators to handle fast exothermic or endothermic spikes. (2) Automated Dosing & Feed Controls: Synchronized syringe or peristaltic pumps deliver reagents based on elapsed time, pH thresholds, or maximum heat-flow dissipation limits (preventing thermal runaway). (3) Torque & Viscosity Monitoring: Real-time feedback from the mechanical stirrer motor tracks shaft torque (N.cm), allowing continuous calculation of slurry viscosity changes or polymerization progress in situ. (4) Data Logging: Continuous recording of Treactor}, Tjacket, stirrer RPM, torque, system pressure, pH, and dosing rate for process analytical technology (PAT) compliance.
