20 Position N-Evap Auto

The automatic 20 position N-EVAP (Catalog # 11220-A) is the most advanced instrument Organomation has developed to date. It combines our classic N-EVAP benchtop evaporator with timed automation technology, and optional nitrogen self-generation. This unit can run in automatic or manual mode due to the integration of our unique pneumatic system. The automatic mode removes samples from the heating medium when the designated time cycle has been completed. You can also manually remove samples when the evaporation process is completed with the flip of a switch. The automatic concentration cycle reduces the likelihood of loss or damage to samples. A digital control system provides the operator with timed control of gas flow and bath temperature.
