The jacketed filtration reactor is a versatile laboratory device, also known as a solid-state reactor.

It is specifically designed for simultaneous chemical reactions and solid–liquid separation. Jacketed filtration reactors are typically constructed from high-temperature and corrosion-resistant materials, such as transparent borosilicate glass, stainless steel, Hastelloy, or graphite. They feature a double-walled jacket for precise temperature regulation and an integrated filtration base for efficient product separation without the need to transfer materials between containers. These characteristics make them highly suitable for research and production applications in pharmaceuticals, chemicals, materials science, and nanotechnology.

The borosilicate glass body offers excellent chemical resistance and visibility during operation, allowing users to monitor the progress of reactions and filtration in real time. The reactor jacket allows circulation of heating or cooling fluids, such as thermal oil, water, or glycol mixtures, enabling precise temperature control over a wide range, typically from –80 °C to +200 °C.

The stainless steel body provides superior mechanical strength, corrosion resistance, and durability, making it ideal for handling corrosive chemicals and high-pressure solid-phase reactions. Unlike glass, stainless steel offers enhanced impact and thermal stress resistance while maintaining structural integrity during prolonged high-temperature operations.

The reactor jacket allows circulation of heating or cooling fluids (e.g., thermal oil, water, or glycol mixtures) to achieve precise temperature control over a wide range, typically from –120 °C to +200 °C. This design ensures uniform heat distribution throughout the reactor, supports high-pressure applications, and enables safe operation during demanding chemical processes.

For applications requiring both chemical resistance and robustness, stainless steel reactors can be further enhanced with PTFE linings or coatings to prevent corrosion and abrasion, ensuring long-term operational reliability while maintaining high performance in solid-phase or multiphase reactions.

To ensure reliability, all critical components—such as the stirring shaft, sealing assembly, and outlet valve—are made from corrosion-resistant materials like PTFE, stainless steel, or fluoropolymer composites. These materials guarantee long-term stability even under harsh chemical conditions or extended use.

Key Design Features

1. Integrated Filtration System

The reactor features a built-in filtration section at the bottom, eliminating the need to transfer mixtures between vessels. The filtration medium can be a sintered glass disc, PTFE filter, or stainless steel mesh. The filtered liquid can be drained directly through a valve, while the solid residue remains in the reactor for washing or drying.

2. Temperature and Pressure Control

The double-walled jacket design ensures uniform heat distribution throughout the reactor. Circulating thermostatic fluid maintains stable reaction conditions, whether for crystallization, precipitation, or extraction. Some models are compatible with vacuum systems, allowing low-pressure filtration and solvent recovery.

3. Efficient Stirring and Mixing

Equipped with an overhead mechanical stirrer, the reactor promotes homogeneous mixing of reactants and prevents sedimentation during solid–liquid reactions. Stirring speed is adjustable to accommodate different viscosities and particle loads.

4. Chemical and Thermal Resistance

Borosilicate glass resists most acids, bases, and organic solvents. Combined with PTFE sealing gaskets, the system provides leak-free operation and prevents cross-contamination between batches.

Typical Applications

Filtration reactors are ideal for reactions that produce solid precipitates or require crystallization, such as the synthesis of pharmaceutical intermediates, fine chemicals, and catalysts. By integrating reaction and filtration into a single system, they minimize material handling, reduce contamination risk, and enhance safety.

Material and Nanoparticle Preparation

Jacketed filtration reactors are commonly used for the preparation of ceramic powders, metal oxides, and nanomaterials. Precise temperature control ensures uniform particle growth and maintains stable physical properties. The integrated filtration system allows rapid separation and cleaning of solid products.

Pilot-Scale and Industrial Research

In scale-up laboratories and pilot plants, jacketed filtration reactors simplify process development. They provide a scalable solution for studying crystallization, filtration kinetics, and solid recovery under reproducible conditions. Optional automation interfaces allow programming of temperature, stirring, and filtration steps for continuous operation.

Operation and Maintenance Notes

For optimal performance, ensure proper circulation of fluids in the jacket before heating or cooling. Avoid rapid temperature changes to prevent glass stress. After each batch, thoroughly clean the reactor and filtration disc using appropriate solvents. Inspect gaskets, clamps, and vacuum seals regularly.

When operating under vacuum or pressure, verify that all connections and valves are securely fastened and rated for the intended conditions. Replace any worn or damaged components immediately to maintain system integrity.
