Organomation 11848 48 Position MULTIVAP Nitrogen Evaporator

The MULTIVAP® blowdown evaporator is ideal for concentrating large batches of samples, and can be used in numerous sample preparation methodologies. These instruments contain 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 toggle switches which allow gas flow to individual rows to be shut off when evaporating batches at less than full capacity.

A heated aluminum dry block provides heat to samples, reaching evaporative temperatures ranging from 30°C to 120°C. Sample blocks are customized for the user’s sample size for maximum and even heat transfer. One set of inserts is included with the instrument. Insert sets for additional tube sizes can be purchased for the 30 and 48 Position models. Since these inserts and heat blocks are made-to-order, precise measurements of the sample vials (or samples of the vials themselves) are needed in order to guarantee the fit.

All models can withstand contact with organic solvents; however acid resistant models are also available for use with corrosive solutions.
