Reactor with Limpet Coils

A Gravity Displacement Autoclave is a reliable sterilization system that uses steam to displace the air inside the chamber through gravity. It is simple to operate and highly effective for sterilizing laboratory instruments, glassware, medical tools, and culture media.

In this method, steam enters the chamber and pushes the air out through a vent, allowing saturated steam to contact every surface for complete sterilization. Gravity autoclaves are widely used in hospitals, research laboratories, and small-scale industrial applications due to their ease of use, cost-effectiveness, and consistent performance.

Built with durable stainless steel and equipped with safety features like pressure controls and locking mechanisms, our gravity displacement autoclaves ensure safe, efficient, and contamination-free sterilization.

A Limpet Coil Reactor features a half-pipe coil (welded on the outer surface of the vessel) through which steam, hot oil, or cooling water is circulated. This design ensures efficient heat transfer and uniform temperature control without direct contact between the heating/cooling medium and the reactants. Combined with an agitator system, it maintains proper mixing, reaction consistency, and process safety.

Polymerization, chlorination, oxidation, and hydrogenation are processes used in the chemical industry.
The pharmaceutical industry includes batch formulations, intermediates, and APIs.
Refining, blending, and catalyst reactions in the petrochemical industry.
Cooking, fermentation, and flavor processing in food and beverages are controlled by temperature.

Provides precise temperature control for sensitive reactions.
High thermal efficiency and energy savings are guaranteed.
No direct contact between the heating/cooling medium and the product.
Strong, durable design with low maintenance needs.
Suitable for both batch and continuous operations.
