stirred tank bioreactor sizing

our factory


These bioreactors are commonly cylindrical, ranging in size from litres to cubic metres, and are often made of stainless steel. . On the basis of mode of operation, a bioreactor may be classified as batch, fed batch or continuous (e.g. a continuous stirred-tank reactor model).

Continuous stirred-tank reactorWikipedia

The continuous stirred-tank reactor (CSTR), also known as vat- or backmix reactor, is a common model for a chemical reactor in chemical engineering.A CSTR often refers to a model used to estimate the key unit operation variables when using a continuous agitated-tank reactor to reach a specified output.
