PEEK Precolumn Filter Kit - High Pressure

PEEK precolumn
  • 100% biocompatible
  • Minimal hold-up volume
  • Replaceable metal-free polyetheylene frits and biocompatible titanium frits encased in PEEK
  • Different porosities

The VICI Jour precolumn filter kit has a standard 10-32 fitting and fits direct to most column types without introducing additional dead volume.

The filter kit protects expensive columns against fine particles, which may otherwise accumulate on the column frit and lead to split peaks and high backpressure.
