The advantages of in-house liquid nitrogen generation in laboratories: Liquid nitrogen (LN₂) is indispensable across a wide range of laboratory and analytical applications — from cryopreservation and sample storage to spectroscopy, electron microscopy, and superconductivity. Yet, for many labs, sourcing LN₂ still means relying on external suppliers, managing delivery schedules, and facing the operational risks of supply interruptions.
As laboratory demands evolve toward greater autonomy, sustainability, and cost efficiency, on-site liquid nitrogen generation has become a practical and forward-thinking alternative. The Cryogen Series by F-DGSi, now available in Greece through The Science Support, exemplifies this shift by offering reliable, plug-and-play solutions tailored to the modern analytical laboratory.
Why Switch to On-Site Liquid Nitrogen Generation?
- Continuous Supply — Zero Downtime
Traditional liquid nitrogen logistics depend on external suppliers and scheduled deliveries. In contrast, an in-house generator enables laboratories to produce LN₂ continuously, ensuring uninterrupted workflows. The Cryogen Series provides a production capacity ranging from 8 to 960 liters per day, allowing labs to scale their production to meet routine or peak operational demands.
- Safety and Risk Reduction
Handling and storing delivered liquid nitrogen cylinders or dewars involves manual transport, pressurized vessels, and associated risks. Instead, the Cryogen Series mitigates these issues by enabling automated, closed-loop production and dispensing, with built-in oxygen monitoring, pressure safety systems, and automatic shutdown features. This significantly reduces exposure to potential cryogenic hazards and eliminates the need for heavy transport or manual transfer of cryogenic vessels.
- Operational Cost Efficiency
While traditional LN₂ supply contracts often involve recurring rental and delivery fees, in-house generation requires only electricity and periodic maintenance. Over time, the total cost of ownership for an LN₂ generator can be considerably lower than that of outsourced supply — particularly for laboratories with consistent demand.
F-DGSi’s energy-efficient economy mode and advanced compressor control further reduce operational costs, aligning with sustainability goals and carbon-footprint reduction strategies.
- Purity and Quality Assurance
High-precision analytical workflows, such as mass spectrometry, SEM/TEM imaging, or cryogenic trapping in gas chromatography, require LN₂ of consistent purity. Indeed, the Cryogen Series delivers ultra-pure liquid nitrogen, generated from filtered ambient air and purified through a PSA (Pressure Swing Adsorption) nitrogen generator combined with a cryocooler. This ensures reproducibility and reliability across analytical processes without the contamination risks associated with delivered LN₂.
- Sustainability and Environmental Benefits
By eliminating transportation, refilling, and cylinder disposal, on-site generation supports laboratories in meeting their ESG (Environmental, Social, and Governance) objectives. For laboratories, this translates into reduced CO₂ emissions, minimized waste, and greener operations.
Liquid nitrogen generation in Analytical and Research Laboratories
Liquid nitrogen is critical in numerous analytical and biotechnological processes:
- Cryogenic grinding and sample homogenization for molecular analysis
- Cooling of detectors and superconducting magnets in NMR and MRI
- Sample storage and cryopreservation in biobanking and IVF laboratories
- Cryo-electron microscopy (cryo-EM) for structural biology
- Elemental and isotopic analysis using ICP-MS and FTIR spectrometry
For all these applications, the Cryogen Series ensures constant availability of high-quality liquid nitrogen, enabling analytical accuracy and uninterrupted operation. Access the Cryogen Series brochure here.
