ECS-KM High Throughput Rotary Solvothermal Reactors (Max. 3 MPa, 260°C), EKMHTRSR

High-throughput rotary solvothermal reactors (often configured as multi-vessel carousel systems or rotating pressure bomb arrays inside forced-convection ovens) accelerate combinatorial synthesis and process screening for advanced functional materials—such as metal-organic frameworks (MOFs), zeolites, battery precursor powders, and nanocatalysts. By mounting multiple miniature autoclaves onto a central rotating carousel, these platforms combine high-throughput batch screening with continuous tumbling agitation to overcome heat and mass transfer bottlenecks typical of static hydrothermal synthesis.

In traditional static solvothermal synthesis (e.g., PTFE-lined stainless steel autoclaves in a box furnace), precursor settling creates localized concentration gradients and non-uniform thermal profiles, often leading to broad particle size distributions or phase impurities. It has the following advantages: (1) Active Agitation in Sealed Vessels: Rotating the entire multi-vessel array continuously flips the reaction chambers end-over-end (typically 5-30 RPM). This keeps insoluble precursors, seeds, or heterogeneous catalysts suspended without needing individual internal stir shafts or magnetic bars in every vessel. (2) Thermal Uniformity: Continuous motion exposes all vessels across the carousel to identical convection airflow, eliminating boundary-layer cold spots across the screening batch. (3) Controlled Kinetics & Crystallite Uniformity: Tumbling prevents dense crystalline products from dropping to the bottom and over-growing, yielding narrow particle size distributions and uniform phase morphology.
