The Laboratory Hydrogen Generator (BIO-0742) produces hydrogen on demand by water electrolysis, so a gas chromatograph or other laboratory instrument can run without hydrogen cylinders. It comes in two models, 300 and 500 mL/min, and both deliver hydrogen above 99.999% purity at an outlet pressure adjustable from 0 to 0.5 MPa (factory setting 0.4 MPa).
The alkaline electrolyte is added once; in daily use the generator only needs distilled water, and it produces hydrogen as soon as it is switched on. Its cartridge-type electrolytic tank uses precious-metal electrode materials that raise electrolysis efficiency, hold the cell temperature constant and extend the tank's service life. Hydrogen leaves through stainless steel tubing, electrolytically polished and ultrasonically cleaned, and passes two purification stages. An over-pressure protection device, and an anti-return device that keeps liquid out of the gas line, protect the instrument downstream. Output flow is stable and tracks demand automatically, and purity does not decay in continuous use.
- 300 mL/min: 0–300 mL/min output, 150 W, 320 × 180 × 370 mm (W × D × H)
- 500 mL/min: 0–500 mL/min output, 250 W, 345 × 185 × 395 mm (W × D × H)
Both models run on AC 220 V ±10%, 50 Hz ±5% (AC 110 V, 60 Hz optional), operate at 10–40 °C and up to 85% humidity, and weigh 10 kg.
How It Works
The generator splits water by electrolysis in an alkaline electrolyte. The alkali is added once; after that the unit only needs distilled water topped up, and switching it on starts hydrogen production. A cartridge-type electrolytic tank with precious-metal electrode materials keeps the cell temperature constant and the electrolysis efficient.
Hydrogen leaves the cell through a stainless steel gas path, electrolytically polished and ultrasonically cleaned, and passes two purification stages. An anti-return device keeps liquid from entering the gas line, and an over-pressure protection device guards the outlet. Output flow is stable and tracks the downstream demand automatically, up to 300 or 500 mL/min depending on the model, at an outlet pressure adjustable from 0 to 0.5 MPa (factory setting 0.4 MPa).

Practical Tips
Allow adequate warm-up time before connecting to sensitive analytical instruments to ensure stable gas output parameters.
Why: Initial operation may show parameter fluctuations that could affect analytical reproducibility.
Verify all gas connections are properly sealed using appropriate leak detection methods before system operation.
Why: Hydrogen leaks pose fire and explosion hazards in laboratory environments.
Monitor consumable levels and replace according to manufacturer schedules to maintain gas purity specifications.
Why: Depleted consumables can compromise hydrogen purity and affect analytical results.
Verify output flow rates and pressures periodically using calibrated measurement devices.
Why: Flow rate accuracy directly affects analytical instrument performance and measurement precision.
Document generator operating parameters when recording analytical data for traceability purposes.
Why: Gas supply conditions can influence analytical results and may be required for regulatory documentation.
Check electrical connections and power supply if the generator fails to start or maintain stable operation.
Why: Power supply issues are common causes of operational problems in electronic gas generators.

Background reading relevant to this product:
What hydrogen purity level does this generator achieve for analytical applications?
Hydrogen purity is above 99.999% on both models, and it does not decay in continuous use.
What are the typical flow rate and pressure output ranges?
0–300 mL/min or 0–500 mL/min, depending on the model, at an outlet pressure adjustable from 0 to 0.5 MPa (factory setting 0.4 MPa).
How frequently does the system require maintenance or consumable replacement?
The alkaline electrolyte is added once; in daily use the generator only needs distilled water topped up. Consult the user manual for other service intervals.
Can this generator supply multiple analytical instruments simultaneously?
Yes, as long as their combined hydrogen demand stays within the model's output, 300 or 500 mL/min, at the pressure they need.
What safety features are included for hydrogen gas handling?
An over-pressure protection device, an anti-return device that keeps liquid out of the gas line, and a stainless steel gas path with two-stage purification.
Is the unit compatible with existing laboratory gas distribution systems?
Compatibility depends on connection types and pressure ratings. Check gas outlet specifications against existing laboratory infrastructure requirements.
