DESCRIPTION
The 24 position N-EVAP is our most adaptable benchtop evaporator. The basic model offers all of the standard features from our N-EVAP line. Additionally, the 24 position N-EVAP offers the most customizable options for your sample preparation needs. The standard sample holder can accommodate samples with an outside diameter of 10-30 mm. However, with the optional 8 position large sample holder, vials with an outside diameter of 30-70 mm can be processed. The 24 position N-EVAP test tube evaporator can also be upgraded to include digital controls for heat and time with the addition of the side control box (Option code -CB).

These economical units provide controlled concentration of sample vials through the application of nitrogen gas within a heated water bath. The dual band spring hoist assembly provides a simple and effective means of removing samples from the heated water bath. The N-EVAP’s circular rotating design permits each sample to be accessible from the front of the instrument for easy insertion and retrieval. The chrome plated needle valves are individually milled from solid brass, enabling precise, uniform adjustments for your nitrogen blow down. This promotes efficient and safe sample reduction with minimal nitrogen waste. Time tested technology and proven construction ensure a long lasting, user-friendly experience.
