The reaction kettle adopts an open-loop design, which is easy to operate and greatly improves experimental efficiency. The maximum working pressure is 20 MPa, and the maximum working temperature is 300°C. Materials available include 316L stainless steel and precious metals, making it suitable for high-viscosity materials. Depending on the quick-opening method, it is divided into two types: lock-type quick-opening and one-button quick-opening.
