A jacketed glass reactor is a container that is designed for controlling temperature of its contents, by using a cooling or heating "jacket" around the vessel through which a cooling or heating fluid is circulated. The jacket has ability to permit the uniform exchange of heat between the fluid circulating in it and the walls of the vessel.Here we offer a wide range of glass reactors with volumes from 500mL to 200L. They can be made into system devices with multi-functional circulating water vacuum pump, diaphragm vacuum pump, low temperature circulating pump, circulating cooler, constant temperature circulator and cooling and heating circulating equipment. It can be used in the experiment and production of chemistry,fine chemical engineering, biological pharmacy and synthesis of new materials.
