Concentration, Crystallization,
Dryness, Separation, and Menstruum Recycle are the basic operations and
processes in pharmaceutical, chemical and Biological trades. In order to enhance the operation efficiency,
film evaporating under negative pressure and constant heating has been proved
to be the most effective way. Rotary
Evaporator, working under this principle, is one efficient evaporating apparatus. It
is very suitable for evaporating solution that is sensitive to heat.
