The laboratory hydrothermal autoclave reactor is a compact, high-pressure reaction vessel designed for chemical synthesis, nanomaterial fabrication, and crystallization processes. It creates a sealed environment where temperature and pressure can be precisely controlled, enabling researchers to replicate natural hydrothermal conditions in the laboratory.

With its stainless steel outer body and PTFE (Teflon) inner liner, this reactor combines mechanical strength with excellent chemical stability, making it one of the most reliable tools for scientific research.

Technical Structure and Design

The hydrothermal reactor consists of the following main components:

• Outer Shell: Made from 304 or 316 stainless steel for high mechanical strength.
• Inner Chamber: Teflon or PPL liner ensures non-reactivity and prevents corrosion.
• Sealing Cap and Gasket: Provides an airtight seal for high-pressure conditions.
• Safety Valve (optional): Ensures safe pressure release during experiments.

This dual-layer construction provides the perfect balance between safety, durability, and chemical inertness.

Working Mechanism

During operation, the sample solution is sealed inside the Teflon liner and placed within the reactor. When heated, internal pressure increases due to solvent vaporization, allowing hydrothermal or solvothermal reactions to occur.

This process helps synthesize crystals, catalysts, oxides, and nanocomposites with controlled morphology, size, and composition.

Operating Instructions

1. Add reactants and solvent to the PTFE liner.
2. Seal the autoclave tightly using the threaded cover.
3. Place the unit inside a laboratory oven and heat gradually.
4. After completion, allow it to cool before opening.
5. Clean the liner and gasket to ensure long-term use.

Safety Notes

• Never exceed the rated limits of temperature or pressure.
• Avoid rapid cooling; allow natural pressure release.
• Wear safety gloves and goggles.
• Keep the autoclave clean and dry when not in use.
