Organomation 6 Position N-EVAP Nitrogen Evaporator

The Organomation 6 Position N-EVAP is a compact and cost-effective sample concentrator designed for simultaneous evaporation of up to 6 samples. Based on the proven N-EVAP technology developed in the 1970s, it ensures reliable and reproducible solvent evaporation using nitrogen gas within a heated bath.

The system supports a wide range of sample sizes – 10–30 mm OD as standard, and up to 30–56 mm OD with an optional holder. The circular rotating design allows easy front access to all samples.
