## 20 Position Auto N-EVAP
Nitrogen Evaporator

#### DESCRIPTION

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.

**Automation**

Samples are raised out of the bath and nitrogen flow is shut off after the timed endpoint has been reached

**Flexible**

An adjustable sample holder design fits a wide variety of sample tubes and vials at once

**Precise**

Digital controls allow exact temperature regulation

**Individualized Control**

Optimize evaporation of diverse samples with individual gas flow control at each vial
