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 | 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 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)...

The automatic concentration cycle reduces the likelihood of loss or damage to samples. A digital control system provides the operator with timed control of gas flowOrganomation’s automatic 20 position N-EVAP® removes samples from the heating medium when the designated time cycle has been completed. The automatic concentration cycle reduces the likelihood of loss or damage to samples. A digital control system provides the operator with timed control of gas flow and bath temperature.
Advantages: - Automation: Samples are raised out of the bath and the gas flow is shut-off after the timed endpoint has been reached
- 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

The heating unit features the digital timer, precise temperature control, and built-in gas pressure gauge provided by our MULTIVAP line. | The triple position MICROVAP® microplate evaporator combines three 96 needle manifolds and three heat blocks into a single platform. The solid aluminum heating units provide consistent temperature for uniform evaporation rates throughout all three plates.
Each 96 needle manifold is equipped with The triple position MICROVAP® microplate evaporator combines three 96 needle manifolds and three heat blocks into a single platform. The solid aluminum heating units provide consistent temperature for uniform evaporation rates throughout all three plates.
Each 96 needle manifold is equipped with its own toggle switch to shut down gas flow when all three microplates are not in use to conserve nitrogen gas, saving laboratories money.
Advantages: - High throughput: Evaporate up to three 96 well plates at once
- Ease of use: Temperature and gas levels are easily set using the digital temperature controller and gas flow meter
- Flexibility: Toggle switches allow gas flow to be turned on and off at each plate
