Nitrogen Helps Control Incubator Oxygen Levels

In IVF (in vetro fertilization), an incubator serves the purpose of protecting and culturing an embryo, hopefully to the point where it can be transplanted, resulting in pregnancy. Maintaining a reduced oxygen level within the embryonic incubator is essential to preserving the embryo inside. In order to reduce the level of oxygen in the incubator, a steady stream of Nitrogen gas is pumped into the incubator's atmosphere at a carefully monitored rate.

How Does a Nitrogen Generator Benefit IVF Incubators?

Having a Nitrogen Generator on site is highly beneficial for facilities that handle embryonic incubators for IVF treatment. Because Nitrogen Generators are consistently producing high-purity Nitrogen from the surrounding air, there is little to no chance of the facility accidentally running out of Nitrogen gas. And because the need for a constant stream of Nitrogen is crucial during this stage of the IVF process, having an on-site Nitrogen Generator can give peace of mind to both the lab technicians, physicians and patients.

Why Nitrogen Gas?

In IVF, the doctors and laboratory technicians try to mimic the conditions of the fallopian tubes and uterus of a fertile female as best they can. Unlike the surrounding air we breathe every day, which consists of 20 percent oxygen, the conditions needed for successful embryonic culture requires only 5 percent oxygen. The introduction of pure Nitrogen into the incubators allows the oxygen to be kept at a controlled level without harming the sensitive embryo inside. The best way to maintain such specific O2 levels is to have a supply of constant, monitored Nitrogen to displace oxygen molecules and preserve the atmosphere.

Nitrogen Supply for Universities and Research Labs

Nitrogen gas is one of the most common elements in the universe. It is estimated to be seventh in total abundance in our galaxy and solar system, and forms approximately 80 percent of the Earth's atmosphere. Because it is so common, and because of its favorable qualities, Nitrogen is used for a variety of tasks and is relied upon for a variety of applications. One such application is laboratory research.

When it comes to creating an atmosphere that is safe, dry, clean and conducive to scientific research, Nitrogen is by far the most effective choice. And because many leading universities serve as starting points for advanced research and laboratory testing, it's no wonder so many of them rely on high-purity Nitrogen gas for their experiments and technical operations. From controlling the atmosphere in order to protect highly sensitive equipment, to sample preparation for chemical analysis, Nitrogen plays a key role in the research lab setting.

Because universities and research labs often require large amounts of Nitrogen to maintain their operations and atmosphere, a Nitrogen Generator is typically used to reduce the risk of accidental run out. Nitrogen Generators are advanced systems that create their own steady supply of Nitrogen gas by separating the N2 molecules from the surrounding air and storing it in a tank for future use.

Nitrogen was first discovered to be a separable component of air in 1772 by Scottish physician Daniel Rutherford. Since then, people have been able to effectively separate Nitrogen molecules from the surrounding air we breathe and apply it to various operations. Although the process sounds highly technical and complicated, Nitrogen Generators can accomplish the task safely, efficiently, and with minimal supervision. Most Nitrogen Generators are fully automated, which means they will begin producing Nitrogen as soon as the sensors pick up a demand downstream. Once the sensors on the Nitrogen Generator activate, the generator will automatically begin the process, using either PSA or Membrane Technology. This can be a much safer, more reliable source for Nitrogen than liquid Nitrogen tanks, or high-pressure cylinders.

Using a Nitrogen Generator can also be a more cost-effective solution for laboratories and university research teams. South-Tek Systems, a leading manufacturer of Nitrogen Generation Systems, has conducted research to estimate the total savings that can be actualized by switching to an on-site Nitrogen Generator. The results indicate that by using a Nitrogen Generator, which produces high-purity Nitrogen gas on demand, a facility's overall Nitrogen costs can be reduced by up to 90 percent!

Other benefits of using a Nitrogen Generator from South-Tek Systems include...
  • Return on investment averages 12-14 months after installation, over bulk liquid Nitrogen.
  • 20 year life expectancy for the system.
  • No missed deliveries, rising gas costs, or expensive contracts to sign.

N2 Gas Purge for Autoclaves, Ovens, and Aluminum Furnaces

Nitrogen gas has a wide range of uses within various industrial applications. One such application is the processing, curing and treating of resins. Resins are used in many different materials, some of which are even used in the aerospace industry, and need to be carefully cured in order to prevent bubbles, deformities and impurities. Nitrogen can be introduced in the treatment process to ensure that autoclaves, ovens and aluminum furnaces can process the product safely and efficiently.

Purging for Autoclaves

In a process known as purging, nitrogen is introduced to displace existing oxygen, moisture or contaminants. In autoclaves, which process industrial parts and equipment, nitrogen is used in place of compressed air to greatly reduce the risk of combustion. Because nitrogen is an inert gas, it is an effective choice for maintaining safe operating procedures. Also, because nitrogen is readily available, it can be a cost-effective solution for facilities that rely on furnaces, ovens and autoclaves for large-scale production.


To further benefit from nitrogen's efficient and safe use, a Nitrogen Generator can be installed at the point of process to effectively generate a supply of N2 gas from the surrounding air. South-Tek Systems is a leading manufacturer of such generators and our sole focus is dedicated to safe, reliable nitrogen generation technology. We are specialists in the N2 generation field, providing a wide range of Nitrogen Generators in various sizes to better serve a multitude of facilities.


The Nitrogen Generators from South-Tek System use the latest technology to separate nitrogen molecules from the air we breathe, which frees the user or facility manager from having to rely on expensive high-pressure gas cylinders, which can run out unexpectedly - not to mention require a costly contract with gas suppliers.

Instead of having to change out nitrogen gas cylinders, having a Nitrogen Generator at the point of process can help your facility run smoothly, with less risk of interrupts and down-time during peak production.

To learn more about South-Tek Systems and how our Nitrogen Generators can benefit your autoclave purging operations, please give us a call at 888-526-6284 or contact us online for more information.
