As a commonly used biochemical instrument, the jacketed glass reactor is extensively used in modern fine chemical, bio-pharmaceutical, scientific research and other industries. It can concentrate, distill, reflux, separate and purify materials under constant speed, constant force and constant temperature, which is a ideal instrument for teaching, experiment, pilot test and production. It is necessary to learn some troubleshooting knowledge of a jacketed glass reactor for its better use.
