LGJ-20Plus Laboratory Freeze Dryer


The LGJ-20Plus laboratory freeze dryer with -120C condenser temperature is designed especially to freeze dry low eutectic point materials such as organic solvents, methanol and ethanol. The ultra-low temperature condenser can effective separate solvents, store them on condenser surface by ice format, or, in some case, liquid phase in tank.
