Nitrogen evaporators are used in a wide range of industries to prepare samples before they are analyzed.

These machines dry and concentrate samples, allowing analyzers such as gas chromatography (GC), high-performance liquid chromatography (HPLC), and mass spectrometry (MS) systems to run tests on them. 

Samples are loaded into the sample holders and the nitrogen gas—often in combination with gentle processes such as dry heat or vortex motion—is applied to remove moisture from the sample. Nitrogen gas flow is often controlled by a flow meter and a built-in pressure regulator.

Due to the overall effectiveness of this evaporation system, it has found uses in a massive array of research verticals. The food, biotech, environmental science, analytical chemistry, and petroleum industries have all found these devices to be instrumental in their research and day-to-day operations. 

Nitrogen evaporators come in several variations that can be tailored to match your specific sample preparation needs.

Nitrogen Blowdown Evaporator Benefits

Nitrogen blowdown evaporators—also known as nitrogen sample concentrators—are used in a range of industries to perform a variety of tasks. While many industries require extremely specialized equipment, nitrogen evaporators are convenient due to their flexibility of use and their customization options. They are typically acid resistant as well, with coating on the instrument and needles protecting it from more volatile samples or solvents.  

Some of the benefits and customizations include:

Sample Positions & Outside diameter

Depending on your throughput needs and endpoint goals, there is a range of sample position options available. The choices can depend on the manufacturer. For example, companies like Organomation include many different choices, from 6- and 24-position to 100-position evaporators.

This provides researchers the ability to control the number of samples they evaporate using gas flow—on it’s own or in combination with heat or wet/dry baths.

Some units can perform high-throughput evaporation of high numbers of smaller sample sizes (ex. 96 well plates). However, nitrogen blowdown is not recommended for large sample sizes, especially when working with volatile or semi-volatile samples. This is due to both the time it takes to dry a solvent and the turbulence the samples undergo.

Thanks to a variety of sample holder options, various flasks and vials with differing diameters can be used to hold samples.


Endpoint Determination

Automatically being able to detect the endpoint of a concentration is an amazing feature. Endpoint determination allows samples to be concentrated to the specific volume needed for the analysis, but doesn’t require the researcher to babysit the test tubes.


Dry Block Heaters

Dry blocks—or heat blocks—are used to speed up the evaporation process.

While stainless steel water baths used to be a necessity, dry block heaters have become a more common addition to these pieces of equipment. Heated water baths lead to condensation which can contaminate samples and often require a fair bit of maintenance.


Mechanical Vortexing

Using mechanical vortexing allows samples to be placed at an angle in the evaporator. This improves the evaporation rate by significantly increasing the surface area of the sample.


Solvent Recapturing

Partly driven by increasing state and federal regulations, many of the evaporators on the market can effectively capture an increased amount of the solvents used in the sample concentration process. This is better for the environment and your bottom line.

Nitrogen is one of the most commonly occurring elements in the known universe, making up somewhere close to 78% of the earth’s atmosphere. While nitrogen naturally occurs in large quantities, fossil fuels, agriculture, and industrial application have led to excess nitrogen in some areas of the world. This excess can affect biodiversity in those regions, causing long-term issues.


We Offer NO2 Evaporator Leases to Fit Every Need

We lease a wide variety of evaporators, from nitrogen to rotary evaporators. If you’re interested in leasing a nitrogen evaporator to prepare samples for gas chromatography, we can help. One of our team members can walk you through the benefits of Excedr’s lease program and provide you with a lease estimate and additional pricing information.

Operating Lease

This off-balance sheet financing structure provides three options at the end of the term. The lessee has the option to return the equipment to the lessor, renew at a discounted rate, or purchase the instrument for the fair market value. Monthly payments are also 100% tax deductible which yields additional monetary savings.


If you recently bought equipment, Excedr can offer you cash for your device and convert your purchase into a long-term rental. This is called a sale leaseback. If you’ve paid for equipment within the last ninety days, we can help you recoup your investment and allow you to make low monthly payments. This also frees up money in your budget rather than tying it down to a fixed asset.
