Organomation 30 Position MULTIVAP Nitrogen Evaporator

The Organomation 30 Position MULTIVAP is a high-capacity dry block nitrogen evaporator designed for parallel evaporation of up to 30 samples.

The system features a rectangular 5×6 gas distribution manifold and a dual post lifting assembly. Nitrogen is directed onto the sample surface, enabling rapid solvent evaporation and efficient concentration.

Each row of 5 samples can be independently 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. Custom-made inserts and blocks ensure optimal heat transfer for specific sample sizes.
