64 Position MULTIVAP
Nitrogen Evaporator


The 64 position MULTIVAP nitrogen blowdown evaporator is a water bath 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 8 samples, which allows individual rows to be shut off when evaporating batches of less than 64 samples. Nitrogen gas flow is also controlled by an adjustable flow meter and a built-in pressure regulator.

The 64 position MULTIVAP parallel evaporator uses a heated water bath to reach evaporative temperatures ranging from 30°C to 100°C. Sample racks are customized within a range of 11-30 mm for the user’s sample size. Please specify sample size (outside diameter and length to nearest 0.1 mm) when placing an order. All models can withstand contact with organic solvents; however acid resistant models are also available for use with corrosive solutions.


Evaporate batches of up to 64 samples, with outside diameters of up to 30 mm


Digital controls allow exact temperature regulation

Optimum Heat Transfer

The water bath provides even heating and optimum heat transfer up to 100°C


Uniform evaporation across all samples with no adjustment needed between runs
