The KSF series high-pressure reaction kettle has a lid that can be lifted and lowered, and is divided into two types: KSF-S manual lifting and KSF-D electric lifting. It mainly consists of the kettle body, kettle cover, magnetic stirrer, heater, valve, feeding port, internal cooling coil, safety blasting device, pressure gauge, control instrument, and lifting device. The KSF series laboratory magnetic stirring reaction kettle is a stirring reaction device for chemical reactions of gas-liquid, liquid-liquid, liquid-solid or gas-liquid solid three-phase chemical materials. It can fully stir various chemical materials under high pressure, vacuum, and temperature, enhancing mass and heat transfer processes. More suitable for stirring reactions in various flammable, explosive, highly toxic, valuable media, and other highly permeable chemical media. It is an ideal leak free reaction equipment for sulfurization, fluorination and other reactions in petroleum, chemical, organic synthesis, polymer material polymerization, food and other processes.
