The 12 position N-EVAP nitrogen evaporator (cat# 11155) is a compact unit that allows for up to 12 samples to be evaporated simultaneously. At each individual sample position, the gas flow can be controlled via a precision needle valve. This is ideal for the simultaneous evaporation of samples with varying evaporation end points. The sample tray has a spring tensioner which allows any test tube between 10-30 mm to be processed without any modifications to the instrument. An optional small sample holder allows samples with an outside diameter of 5-16 mm to be processed.

First introduced in 1959 as The Meyer N-EVAP, the 12 position N-EVAP (cat# 11155) was the first nitrogen dryer created by Organomation. It has proven to be an extremely durable, time tested and highly affordable member of Organomation’s N-EVAP line. These economical units provide controlled concentration of sample vials through the application of nitrogen gas within a 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.
