Micro GPN-300 Nitrogen Generator: Reliable On-Demand Lab Gas Solution for Analytical Precision
The Micro GPN-300 Nitrogen Generator is a transformative lab gas system engineered to replace traditional high-pressure nitrogen cylinders, delivering safe, cost-effective, and high-purity nitrogen for critical analytical instruments. Designed for modern laboratories, it integrates seamlessly with Gas Chromatographs (GC), FT-IR Spectrometers, TOC Analyzers, NMR systems, and Thermal Analyzers, ensuring uninterrupted performance while slashing operational costs.
Key Features & Advantages
- Electrolytic On-Demand Generation: Eliminate Cylinders, Enhance Safety
The GPN-300 employs a dual-cathode stainless steel electrolytic cell to produce nitrogen directly from purified water and electricity, eliminating reliance on high-pressure cylinders. This technology mitigates risks of leaks, storage hazards, and delivery delays, while enabling instant start-up and continuous output. Labs gain operational flexibility, reduce administrative burdens (e.g., cylinder rentals, logistics), and enhance workplace safety.
- Ultra-Low Maintenance & Long-Term Cost Savings
Operating the GPN-300 is remarkably simple: periodic refills of high-purity deionized (DI) or distilled water into its integrated reservoir are the primary requirement. Unlike cylinder gas, which incurs recurring delivery and rental fees, the generator minimizes long-term costs with minimal consumables. This translates to significant savings and reduced administrative overhead for lab managers.
- High Purity & Critical Safety Assurance
Equipped with third-stage refinement, the GPN-300 consistently delivers nitrogen purity ≥99.5%, meeting the demands of sensitive analytical applications. A built-in anti-backflow device prevents reverse gas or liquid flow from connected instruments into the generator, protecting both the system and expensive lab equipment (e.g., GCs, NMRs) from contamination or damage.
- Extended Uninterrupted Operation
Its large-capacity water tank supports continuous operation for days (depending on usage), enabling unattended workflows, overnight runs, and high-throughput environments. Labs maintain productivity without frequent water checks, ideal for 24/7 analytical processes.
- Disposable Purification Tube: Reliability & Ease
The generator features a disposable stretch-mold purification cartridge with minimal leakage points (unlike traditional systems with multiple fittings). Replacement is quick and tool-free, ensuring consistent gas purity and reducing downtime. This design enhances system reliability and simplifies maintenance.
