BenchTop Pro Usage
BenchTop Pro freeze dryers are mechanically refrigerated condenser modules that
can be utilized as freeze dryers, as well as cold traps and for initial product freezing.
When used in freeze-drying mode, the BenchTop Pro can effectively remove up to
99% of product moisture.
Cold Trap Condenser Module
When using a vacuum concentrator or gel dryer with your BenchTop Pro unit, the
condenser module can be used as a cold trap, trapping vapors driven off the product
before they reach the vacuum pump. To configure a BenchTop Pro unit for a cold trap
application, replace the condenser cover plate or adapter plate with a cold trap
adapter plate and a ¾-inch stainless steel port. For more information, refer to
Chapter
4: Cold Trap Condenser.
Note: A low condenser temperature is required when trying to trap organic solvents.
