The crystallization filtration reactor is a solid phase reactor, which is a commonly used biochemical instrument. It combines the functions of a reactor and a filter. It is mainly used in modern fine chemicals, biopharmaceuticals, scientific research experiments and other industries. It can be used for stirring, filtration, and suction filtration. , Polypeptide synthesis, crystallization, pyrolysis and other processes, using vacuum negative pressure for suction filtration, high borosilicate glass kettle body, high transparency, convenient to observe the experimental process, is an ideal instrument for teaching, small test, pilot test, production.
