    30 Position MULTIVAP
    Nitrogen Evaporator

    DESCRIPTION

    The 30 position MULTIVAP nitrogen blowdown evaporator 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 5 samples, which allows individual rows to be shut off when evaporating batches of less than 30 samples. Nitrogen gas flow is also controlled by an adjustable flow meter and a built-in pressure regulator.

    The 30 position MULTIVAP parallel evaporator uses a heated aluminum dry block to reach evaporative temperatures ranging from 30°C to 120°C. An unheated version is available for evaporations that will be performed at ambient temperatures. Sample blocks are customized for the user’s sample size for maximum and even heat transfer. Inserts can be customized for sample vial outside diameters of 10-30 mm.

    One set of inserts is included with the instrument. Since these inserts and heat blocks are made-to-order, we will request that you deliver us three sample vials for each unique vial size upon placing an order for a 30, 48 or 80 Position MULTIVAP. In situations where shipping sample vials to Organomation is not possible, we need precise measurements of your sample vials to be taken. All models can withstand contact with organic solvents; however acid resistant models are also available for use with corrosive solutions.
