Organomation 20 Position Auto N-EVAP Nitrogen Evaporator

The Organomation 20 Position Auto N-EVAP is the most advanced nitrogen evaporator developed by Organomation. It combines the classic N-EVAP system with timed automation and optional nitrogen self-generation.

The instrument operates in both automatic and manual modes using an integrated pneumatic system. In automatic mode, samples are removed from the heating bath at the end of the cycle, reducing the risk of sample loss or damage.

A digital control system provides precise control of gas flow and bath temperature, ensuring safe and reproducible evaporation of up to 20 samples simultaneously.
