Reactor Vessel

• Material: Often made from materials that are resistant to the chemicals being used, such as glass or stainless steel. The choice of material depends on the chemicals involved and the operating conditions.
• Design: The reactor vessel may be equipped with features to facilitate crystal growth, such as a large surface area or specific geometries to encourage nucleation and crystal growth.

Temperature Control

• Heating/Cooling Systems: The reactor is typically equipped with heating and cooling systems to maintain precise temperature conditions, which are crucial for controlling the crystallization process.
• Temperature Sensors: Monitors the temperature within the reactor to ensure it stays within the desired range for optimal crystal formation.

Agitation/Mixing

• Stirring Mechanism: Includes a mechanical or magnetic stirrer to ensure uniform mixing of the solution. This helps in maintaining a consistent concentration of the solute and promotes uniform crystal growth.
• Adjustable Speed: The stirring speed can be adjusted to influence the size and quality of the crystals.

Pressure Control

• Pressure Management: Some crystallization processes may require pressure control. The reactor may include pressure relief valves and other mechanisms to manage and monitor pressure.

Sampling and Harvesting

• Sampling Ports: Allows for periodic sampling of the solution to monitor the crystallization process and quality of the crystals.
• Harvesting Mechanism: Features for separating and harvesting the crystals from the solution once the crystallization process is complete.

Instrumentation and Controls

• Control Panel: Used to adjust and monitor temperature, pressure, and stirring speed. Modern reactors may feature digital controls and programmable settings.
• Sensors: Includes sensors for real-time monitoring of temperature, pressure, and sometimes concentration.

Cleanability

• Design for Cleaning: The reactor is designed for easy cleaning to prevent contamination between batches and ensure purity in the crystallization process.
