 · For larger reactors,stainless steel is used. 5. 2. Standard geometry of a stirred tank bioreactor • A stirred tank reactor will either be approximately cylindrical or have a curved base. A curved base assists in the mixing of the reactor contents. • Stirred tank bioreactors are generally constructed to standard dimensions. Reactor Theory and Practice Continuous Flow Stirred Tank Reactor (CFSTR) A Continuous Flow Stirred Tank Reactor (CFSTR) is one in which the contents are stirred so uniformly that it is assumed that no variation or concentration gradients exist within the vessel. In theory, any sample taken from the overflow of the reactor will be identical with any sample taken from within the vessel.

Continuous stirred tank reactors (CSTRs), or ideal stirred tank reactors, are frequently used in the chemical and biochemical industries. This reactor type operates at steady state and because of its good mixing properties, it is assumed that the composition throughout the reactor is uniform. Stirred Reactor is the most common method of extracting herbs and other solids. The material is ground up and placed in a vessel of heated solvent and stirred to get maximum exposure and mixing between the material and the solvent. How it works: The Eden Labs method uses the same basket that is used for Coldfinger and steam distilling.
