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 | 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....

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)...

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 | 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. |
