The Organomation 9 Position MULTIVAP is a high-temperature dry block nitrogen evaporator designed for large volume sample evaporation.
The system features a rectangular 3×3 gas distribution manifold and a dual post lifting assembly, allowing easy adjustment of needles or pipettes. Nitrogen is directed onto the sample surface, enabling rapid solvent evaporation and efficient sample concentration.
Each row of three positions can be individually switched on/off, allowing significant nitrogen savings when processing fewer samples.
The system operates with a heated aluminum dry block (30–120 °C) or as an ambient (unheated) version.
