Nov 25, 2016 Remember, when the condenser on your evaporator is 20 degrees Celsius cooler than your sample, it will condense most of the vapors leaving the evaporator. That means that a small pump with modest pumping capacity – 1 cfm or less – will provide enough pumping to manage the residual vapors that reach the pump from most benchtop evaporators.
