A Continuous Stirred Tank Reactor (CSTR) is a reaction vessel in which reagents, reactants and often solvents flow into the reactor while the product (s) of the reaction concurrently exit (s) the vessel. In this manner, the tank reactor is considered to be a valuable tool for continuous chemical processing. CSTR reactors have effective mixing ...

Description. Ai R-series single/dual jacketed glass reactors are designed for synthetic reaction of different types of materials in a controlled temperature and vacuum environment. Each reactor features adjustable stirring speeds and a constant pressure feeding funnel that allows you to add material to the vessel at a uniform and controlled speed.

does not require controller tuning except at a lower level to track the reactor temperature or antisolvent addition rate (which can be done by most commercially available water baths or solvent pumps). Its simplicity greatly reduces the time needed to develop a recipe for batch crystallization. Further work

Fig 3: ‘Crash cooling’ crystallization. This method is fast and simple but is not an efficient means of crystallizing CBD isolate as the precipitate forms rapidly and entraps other components. These may include THC, pesticides, solvent, and or any other components that were present in the original distillate.
