Product Description

The LABMAN GGN303 is a laboratory nitrogen generator with an electrolytic cell that supplies nitrogen at up to 300 mL/min and 0.4 MPa with oxygen at 3 ppm or less. It replaces bulky nitrogen cylinders next to the instrument and includes liquid circuit, gas purification and flow display.

Key features

  • Electrolytic cell design replaces bulky nitrogen gas cylinders
  • Clamp-type electrolytic separation cell with high gas production and good heat dissipation
  • Automatic drain for 10 minutes, then switches to gas production
  • Easy to operate with LED flow display
  • Molecular sieve is regenerated in a muffle furnace at 250–300°C for 24 hours
