Micro GPH-300 Hydrogen Generator: Safe, Pure, On-Demand Hydrogen for Your Lab

Eliminate the hazards and hassles of traditional hydrogen cylinders with the Micro GPH-300 Hydrogen Generator. Engineered specifically for demanding laboratory environments by our expert gas source team, the GPH series delivers a consistent stream of ultra-pure hydrogen right at your bench. Its compact footprint, unwavering reliability, exceptional safety features, and outstanding gas purity (99.99%) make it the preferred choice for chromatography (GC, GC-MS), fuel cell research, synthesis, and countless other applications requiring high-purity H₂.

Why Choose the Micro GPH-300 Over Traditional Cylinders?

The GPH-300 fundamentally transforms how labs access hydrogen gas:

1. Unmatched Safety & Convenience: Replace high-pressure hydrogen cylinders entirely. This eliminates the inherent risks of cylinder storage, handling, and transportation. No more waiting for deliveries or managing returns – generate hydrogen on-demand, instantly upon startup, precisely when and where you need it. Enjoy unparalleled flexibility and peace of mind.
2. Extremely Low Operating Costs: Experience significant savings. The primary consumable is high-purity deionized water (Resistivity ≥1 MΩ/cm). Forget recurring cylinder rental fees, delivery charges, and the hidden costs associated with cylinder management. Operational expenditure is dramatically reduced.
3. Continuous, Uninterrupted Operation: Featuring a generous 3-liter integrated water tank, the GPH-300 can run continuously for several days on a single fill. This ensures your critical processes, like overnight GC runs, proceed without interruption for water replenishment.
4. Reliability Engineered In: Robust construction prioritizes dependable performance. Key features include a disposable, stretch-formed purification tube, minimizing potential leakage points and enhancing long-term integrity. Dual one-way valves provide critical dual protection against dangerous backflow into the system.
5. User-Centric Design & Control: Monitor operations effortlessly via the digital display, which shows real-time hydrogen production rates. This intuitive interface simplifies monitoring instrument status and aids significantly in rapid fault diagnosis should it ever be needed.
6. Compact & Efficient: Designed for space-conscious labs, the GPH-300 fits effortlessly onto or under a bench, freeing up valuable workspace typically occupied by bulky gas cylinders and associated manifolds.

Frequently Asked Questions (FAQ)

• Q: What applications is the GPH-300 suitable for?
  • A: It's ideal for any lab requiring a reliable, pure source of hydrogen gas. Primary uses include Gas Chromatography (GC & GC-MS carrier or detector gas), fuel cell testing, catalyst research, synthesis reactions, and as a replacement for carrier/detector gas cylinders in various analytical instruments.
• Q: How often do I need to refill the water tank?
  • A: With its 3-liter capacity and typical consumption rates, one fill generally provides several days (often 5-7 days or more) of continuous operation at maximum output (500 ml/min). Actual duration depends on your specific flow rate usage.
• Q: Does it require any special maintenance?
  • A: Routine maintenance is minimal. The key tasks are keeping the water tank filled with high-purity deionized water (resistivity ≥1 MΩ/cm) and periodic replacement of the disposable purification cartridge (lifetime varies significantly based on usage and air quality, often 1-3 years). The electrolysis cell itself is designed for long-term use.
• Q: Is the hydrogen purity guaranteed?
  • A: Yes, the GPH-300 consistently delivers hydrogen gas with a purity exceeding 99.99%, meeting the stringent requirements of sensitive laboratory instruments like GC-MS. This purity relies on using water meeting the specified resistivity requirement.
• Q: How does it improve safety compared to cylinders?
  • A: It eliminates major risks: no high-pressure bulk gas storage, no handling/transportation of heavy cylinders, no risk of sudden valve failures releasing large gas volumes. Hydrogen is generated at low pressure only as needed. The dual one-way valves prevent dangerous backflow scenarios.
• Q: What happens if the water runs out?
  • A: The generator features safety mechanisms and will typically shut down automatically if the water level becomes too low to prevent damage to the electrolysis cell. An alert will usually be displayed.
