Type Back Pressure Regulator Assembly

Bubbles enter the detector's flow cell, they can cause erratic baseline readings and loss of sensitivity. By placing a back pressure regulator (BPR) after the detector, the fluid remains under sufficient compression after leaving the column to prevent most bubbles from forming and thus helping to ensure a smoother baseline and increased sensitivity.

  • Standard versions, low-volume versions, and adjustable version available
  • Flow-independent pump preload for greater pump efficiency
  • Proven out-gassing protection
  • Multiple pressure ratings
  • 2,000 to 5,000psi (138 to 345 bar)
  • Biocompatible/chemically resistant materials
  • Only 6μLmaximum internal swept volume
  • Designed for multi-detector applications
  • 100% Biocompatible, inert materials
  • Replacement cartridges and holders sold separately
