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 30 position MULTIVAP® uses a heated aluminum dry block to reach timed evaporative temperatures ranging from 30°C to 120°C. This method results in rapid solvent evaporation. The sample block inserts are customized for the user’s sample size for maximum and even heat Ideal for batch processing, the 30 position MULTIVAP® uses a heated aluminum dry block to reach timed evaporative temperatures ranging from 30°C to 120°C. This method results in rapid solvent evaporation. The sample block inserts are customized for the user’s sample size for maximum and even heat transfer. Inserts can be customized for sample vial outside diameters of 10-30 mm.
Advantages: - Capacity: Evaporate batches of up to 30 samples, with outside diameters of up to 30 mm
- Precise: Digital controls allow precise temperature regulation
- Wide Temperature Range: The temperature is controlled up to 120°C to accomplish evaporation of solvents with higher boiling points
- Cost-Effective: Conserve gas by using ON/OFF valve for rows not in use
Optional features: 220 volt wiring, acid resistant coating, needle guide plate for small tubes 15mm and under, Pasteur pipette adapters in place of needles....

It includes a heated water bath with timed evaporation to reach 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. Sample racks are customized within a range of 11-30 mm for the user’s sample size.
Advantages: - Capacity: Evaporate batches of up to 64 samples, with outside diameters of up to 30 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

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
