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 34 position N-EVAP® nitrogen evaporator offers a large number of sample positions, without compromising any of the classic N-EVAP features. This time-tested, durable system provides one of the least expensive prices per position of all our N-EVAPs. The evaporative system, along with Organomation's 34 position N-EVAP® nitrogen evaporator offers a large number of sample positions, without compromising any of the classic N-EVAP features. This time-tested, durable system provides one of the least expensive prices per position of all our N-EVAPs. The evaporative system, along with the standard flow control and pressure reducing regulator, enables the operator to achieve the desired level of concentration with efficient nitrogen usage. The dual band spring hoist assembly ensures easy and effective operator use.
This instrument includes a side control box, which provides timed and digitally controlled water bath temperatures to produce even evaporation rates. The pressure regulator and timer combine to allow timed automatic gas flow cut off which slows evaporation to a minimum once the timed cycle has been completed. In order to prevent damage to delicate samples, the timer also provides the option for the heat to shut off once the cycle is complete.

Read More | The 9 position MULTIVAP® uses a heated aluminum dry block to reach timed evaporative temperatures ranging from 30°C to 120°C. The sample block is built to fit beakers with an outside diameter of 50 mm, and 9 beakers are included with the instrument. If another sample size is to be used, inserts can The 9 position MULTIVAP® uses a heated aluminum dry block to reach timed evaporative temperatures ranging from 30°C to 120°C. The sample block is built to fit beakers with an outside diameter of 50 mm, and 9 beakers are included with the instrument. If another sample size is to be used, inserts can be purchased and customized for your sample. All models can withstand contact with organic solvents. Acid resistant models are also available for use with corrosive solutions.
Advantages: - Capacity: Evaporate samples of up to 100ml each
- 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 include: 220v wiring, acid resistant coating on instrument and needles, and Pasteur pipette adapters in place of needles....

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

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
