Nitrogen evaporators are used to prepare samples for analysis. Used in many industries, such as food, biotechnology, analytical chemistry, petroleum, and environmental sciences, nitrogen evaporators dry and concentrate samples so that tests like mass spectrometry, gas chromatography, and high-performance liquid chromatography (HPLC) can be performed on them. Samples are loaded into the nitrogen evaporator and then nitrogen blowdown is used, sometimes in conjunction with heat, to rid the sample of moisture. There are variations among nitrogen evaporators, including how many sample positions it contains, whether it uses wet or dry baths, if it needs hood space or not, and whether it provides heat as well as nitrogen blowdown to evaporate the samples.

| Description | Ideal for batch processing, the 100 position MULTIVAP® nitrogen evaporator uses a heated water bath to reach evaporative temperatures ranging from 30°C to 100°C. The manifold delivers nitrogen gas to the needles or glass pipettes, which direct the gas onto the sample’s surface. This method results Ideal for batch processing, the 100 position MULTIVAP® nitrogen evaporator uses a heated water bath to reach evaporative temperatures ranging from 30°C to 100°C. 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 10 samples, which allows individual rows to be shut off when evaporating batches of less than 100 samples. Nitrogen gas flow is also controlled by an adjustable flow meter and a built in pressure regulator.
Advantages: - Capacity: Evaporate batches of up to 100 samples, with outside diameters of up to 22 mm
- Precise: Digital controls allow precise temperature regulation
- Optimum Heat Transfer: The water bath provides even heating and optimum heat transfer up to 100°C
- Cost-Effective: Conserve gas by using ON/OFF valve for rows not in use

At each individual sample position the gas flow can be controlled via a precision needle valve. The sample tray has a spring tensioner which allows any Organomation's 12 position N-EVAP® nitrogen evaporator is ideal for the simultaneous evaporation of samples with varying evaporation end points. At each individual sample position the gas flow can be controlled via a precision needle valve. 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.
Advantages: - Small Footprint: N-EVAP Model# 111 has the smallest footprint of all the N-EVAPs
- Flexible: A small sample holder option can be added to accommodate vials with a smaller outside diameter in the range of 5-16 mm
- Gentle: N-EVAP nitrogen evaporators combine nitrogen blow down with a heated bath to gently concentrate delicate samples
- Individualized Control: Gas flow can be controlled at each sample position via needle valves
Optional Features: 220v wiring harness (Option Code# -2), Z-Purge/intrinsically safe purge case (Option Code# -Z), Acid resistant coating on instrument and needles (Option Code# -RT)...
