ABSTRACT:
A new and improved corrosion resistant condenser is provided, adapted for use with a freeze drying system for dehydration of materials with relatively high concentrations of acids or bases. The condenser includes unique heat transfer means for uniform transfer of heat flow between the outer surface of the condenser and a corrosion resistant condensing trap disposed inside the condenser, which condensing trap may be readily removed from the system and immediately replaced in preparation for another freeze drying procedure.
