Stainless Steel Precolumn Filter - Ultra-High Pressure

Stainless precolumn filter
  • UHPLC (up to 1375 bar / 20,000 psi)
  • Minimized hold-up volume
  • Four porosity options
  • Fewer connections compared to in-line filters
  • Works with 1/16" column connections from all manufacturers

VICI Jour's stainless steel precolumn filter is based on our well-known in-line filter. The design of this precolumn filter reduces the number of connections compared to a standard in-line filter, increasing the stability and reducing the potential of leakage.

The small bore sizes (0.15 mm in the nut/body and 0.13 mm in the tubing) guarantee a very small (virtually zero) hold-up volume.

With minimal dead volume and available frit porosities of 0.2, 0.5, 2, or 5 µm, these in-line filters are the best column protectors.
