Liquid Nitrogen Generators

Make yourself independent from long delivery hassles

Liquid nitrogen is typically produced at large industrial quantities and transported in cryogenic containers. Although this approach has been widely adopted, it has increasing limitations. Fluctuations in supply, storage capacity and transport delays make constant provision far from guaranteed. What may seem like a practical solution at first, often leads to significant operational challenges. Safety risks, logistical complications and purity concerns quickly become part of daily operations. In addition, storage limitations and escalating costs from rental fees, delivery charges and inevitable product loss are difficult to avoid.

Our solution? Make your own high-quality liquid nitrogen, anywhere, anytime!

Labtech offers a complete line of Liquid Nitrogen Generators that allow you to produce from 8 up to 80 liters per day.
Our Generators were designed and developed to offer a safer and more efficient alternative to deliveries. This will remove the issues related to liquid nitrogen deliveries, costs and problems with evaporation lost.

With an onsite generator, you regain control, reduce risk and ensure a stable nitrogen supply tailored to your exact needs. Experience first-hand the convenience of having the generator in your lab without delivery hassles.
Never run out of liquid nitrogen!

Easy to use

Turn the valve and dispense.
The system is designed for effortless daily operations. Once liquefaction is complete, dispensing LN₂ is as simple as turning a valve.

Simple dispensation

Thanks to the integrated hose system, liquid nitrogen can be dispensed directly into the tank with precision and control. Every aspect of dispensation is designed with convenience and safety in mind.

Compact, efficient storage

Optimized for your space and workflow.

Sustainable production

Generate only what is required, minimizing waste and your environmental impact.

Proven technology, unmatched reliability

Our Liquid Nitrogen Generator is built on proven cryogenic technology to provide a continuous supply of high-purity LN₂ directly at your facility.
At its core is an integrated Air Compressor and multi-stage filtration system, ensuring clean, dry air as the starting point. Using Pressure Swing Adsorption (PSA) with Carbon Molecular Sieve (CMS) technology, nitrogen is efficiently separated from other gases to ensure reliable purity.

The gas is then cooled by a high-efficiency cryorefrigerator. The latter is equipped with a helium-based cold head and liquefied at its boiling point of –196.76 °C inside the built-in Dewar tank. The liquefied nitrogen is stored safely and can be dispensed easily through the integrated hose. A smart level indicator monitors storage levels and automatically pauses production when full. This, optimizing performance and operational safety.

Engineered for reliability and minimal maintenance, our LN Generator offers a fully autonomous solution to your needs. You will gain immediate access to a safe, efficient, sustainable and reliable supply: no deliveries, no delays, no compromises!

Main Applications

First liquefied at the Jagiellonian University on April 15, 1883 by Polish physicists Zygmunt Wróblewski and Karol Olszewski, the liquid nitrogen has seen constant and unstoppable use in countless fields.
