Recommended Use

The LPG-3400XRS pump is recommended for use within UltiMate 3000 XRS systems to take advantage of long, ultra-high resolution columns requiring support for pressures up to 125 MPa (18,130 psi, 1250 bar).

Features

  • Serial dual-piston operating principle, low-pressure gradient proportioning
  • Support of operating pressures of up to 125 MPa (18,130 psi/1250 bar) at flow rates of up to 2mL/min
  • Reliable vacuum degassing with an internal four-channel micro membrane degasser
  • Active rear-seal wash to maximize seal lifetime and instrument uptime
