An autoclave is a specialized pressure vessel designed for processes requiring high-temperature and high-pressure conditions, such as sterilization, vulcanization, curing, or composite material production. Unlike reactors (used for chemical synthesis), autoclaves focus on controlled thermal and pressure treatments to achieve material transformation or sterilization.

Key Features of Autoclaves*
1. Applications

• Sterilization of medical instruments and laboratory equipment.
• Vulcanization of rubber products.
• Curing composites (e.g., carbon fiber components in aerospace).
• Food processing (e.g., retort sterilization for canned goods).

• **Vertical Autoclave**: Compact, space-efficient, suitable for small batches.
• **Horizontal Autoclave**: Larger capacity, ideal for industrial-scale operations.
• **Benchtop Autoclave**: Portable, used in laboratories or clinics.

• **Stainless Steel**: Most common for corrosion resistance and durability.
• **Carbon Steel with Coatings**: Cost-effective for non-corrosive environments.

4. Heating Methods:

• **Steam Heating**: Direct steam injection for rapid temperature rise.
• **Electric Heating**: Precise temperature control via electric elements.
• **Thermal Oil Circulation**: Uniform heat distribution for sensitive processes.

• Pressure relief valves and rupture discs.
• Automated temperature/pressure interlocks.
• Double-door systems for contamination control.
