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 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:
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.
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 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.
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.
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.
Our lease agreements are founder-friendly and flexible, helping you preserve working capital, strengthen the cash flow of your business, and keep business credit lines open for expansions, staffing, and other crucial operational expenses and business development opportunities.
Leases range from 2 to 5 years. Length will depend on several factors, including how long you want to use the equipment, equipment type, and your company’s financial position. These are standard factors leasing companies consider and help us tailor a lease agreement to fit your needs.
We don’t carry an inventory. This means you’re not limited to a specific set of manufacturers. Instead, you can pick the equipment that aligns with your business goals and preferences. We’ll work with the manufacturer of your choice to get the equipment in your facility as quickly as possible.
Bundle preventive maintenance and repair coverage with your lease agreement. You can spread those payments over time. Easily maintain your equipment, minimize the chances something will break down, repair instrumentation quickly, and simplify your payment processes.
At the end of your lease, you have multiple options. You can either renew the lease at a significantly lower price, purchase the machine outright based on the fair market value of the original pricing, or call it a day and we’ll come the pick up the equipment for you free of charge.
Our leases do not include loan-like terms, which can be restrictive or harmful in certain situations. We do not require debt covenants, IP pledges, collateral, or equity participation. Our goal is to maximize your flexibility. When you lease with us, you’re collaborating with a true business partner.
Our underwriting is done in-house. You can expect quicker turnaround, allowing you respond to your equipment needs as they arise. We require less documentation than traditional lenders and financiers and can get the equipment you need in operation more quickly.
