Choosing a Nitrogen Generator for Sample Preparation: Organomation vs. Peak vs. Parker

In laboratories focused on sample preparation, especially in workflows involving nitrogen blowdown evaporation, the need for a consistent, high-flow nitrogen supply is non-negotiable. Traditionally, many labs have relied on gas cylinders to meet this demand, but with rising operational costs and safety concerns, on-site nitrogen generators have become a more efficient and sustainable alternative.

This post compares three leading nitrogen generators for sample prep applications:

- Organomation's NITRO-GEN+
- Peak Scientific's Genius XE 35
- Parker's NitroFlow Lab

Each unit supports nitrogen evaporation techniques, but there are key differences in cost, performance, and practicality that may influence your decision.

Cost Efficiency

One of the primary considerations for any lab is cost. While all three models include built-in compressors, removing the need for external air sources, the NITRO-GEN+ is designed to offer maximum value. It provides competitive performance at a lower initial investment, making it ideal for labs seeking to stretch their budget without compromising reliability.

In contrast, the Peak Genius XE 35 and Parker NitroFlow Lab are both positioned as premium units with added features that may not be necessary for routine sample preparation tasks.

Performance in Evaporation Workflows

Sample prep workflows often require high flow rates to support multiple nitrogen blowdown evaporators or multitasking across instruments. Here's how the three units stack up:

All three units meet the pressure and flow demands for evaporation, but the NITRO-GEN+’s 35 L/min output ensures compatibility with multiple evaporators or high-volume workflows.

The slightly lower purity (99%) is more than sufficient for nitrogen blowdown applications, where purity above 98% is typically acceptable. Higher-purity models, like those from Peak and Parker, may be better suited for ultra-sensitive analytical methods, but are not essential for evaporation.

Physical Specifications and Usability

Warranty and Support

Warranty coverage is an important consideration, especially for high-throughput labs. Organomation’s 2-year/8,000-hour warranty on the NITRO-GEN+ provides peace of mind, aligning with what most labs expect for mission-critical equipment.

Conclusion

If your lab relies on nitrogen for evaporation, concentration, or solvent removal, the Organomation NITRO-GEN+ offers an ideal balance of performance, reliability, and cost-effectiveness. While the Peak and Parker units offer slightly higher purity and interface enhancements, these features may not be necessary for most sample preparation workflows.

For labs looking to increase efficiency, reduce gas cylinder costs, and maintain reliable evaporation performance, the NITRO-GEN+ stands out as a smart, practical investment.
