Organomation 11848 48 Position MULTIVAP Nitrogen Evaporator

Call for Price

The 48 position MULTIVAP nitrogen evaporator (Catalog# 11848) is a high temperature dry block model. This instrument contains a rectangular gas distribution system mounted on a frame and dual post assembly. The manifold delivers nitrogen gas to the needles or glass pipettes, which direct the gas onto the sample’s surface. This method results in rapid solvent evaporation and sample concentration. In order to conserve nitrogen gas, the manifold has a toggle switch for every row of 6 samples, which allows individual rows to be shut off when evaporating batches of less than 48 samples. Nitrogen gas flow is also controlled by an adjustable flow meter and a built in pressure regulator.


  • Capacity: Evaporate batches of up to 48 samples, with outside diameters of up to 22 mm
  • Precise: Digital controls allow precise temperature regulation
  • Wide Temperature Range: The temperature is controlled up to 120°C to accomplish evaporation of solvents with higher boiling points
  • Cost-Effective: Conserve gas by using ON/OFF valve for rows not in use
