The 24 position N-EVAP (Catalog # 11250) is our most popular nitrogen evaporator. Time tested technology and proven construction insure a long lasting, user-friendly experience. This compact and robust unit offers double the capacity of our 12 position N-EVAP, yet requires minimal bench space. The dual band spring hoist assembly provides a simple and effective means of removing samples from the heated water bath. The rotary sample holder manifold assembly allows for easy insertion and removal of all samples from the front of the evaporator. If wide mouth beakers are used with our optional 8 position sample holder, two gas needles can be applied to a specific sample to accelerate the evaporation rate. Evaporation of small samples can be achieved with or without the heated water bath if desired. Ultra high temperature dry bath and acid resistant models are also available. All units are engineered to UL specifications for laboratory use. Please feel free to contact us for any specific questions about these instruments.
