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 | This instrument is based on our dry block MULTIVAP product line and is customized to hold two 96 well microplates. The heating unit features the digital timer, precise temperature control, and built-in gas pressure gauge provided by our MULTIVAP line. | 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

The outer ring has 30 positions and can accommodate samples with an outside diameter of 10-19 mm. The inner ring has 15 positions and can accommodate samples with an outside diameter of 10-30 mm.
This time-tested, durable system provides the least expensive price 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 unique dual band spring hoist assembly ensures easy and effective operator use.
This instrument includes a side control box. Timed, digitally controlled water bath temperatures provide 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. The heat can also be shut off with the gas after a timed cycle.... Read More | The 64 position MULTIVAP® is best for batch processing.

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
