Stainless Steel In-Line Filter - Ultra-High Pressure

Stainless in-line filter
  • UHPLC (up to 1375 bar / 20,000 psi)
  • Minimized hold-up volume
  • Two bores, for analytical and semi-prep flow rates
  • Four porosity options

The stainless steel in-line filter has virtually no hold-up volume and can be used in various applications without significant band broadening or loss of efficiency.

Stainless in-line filter

The 0.25 mm bore versions are intended for analytical use between autosampler/injection valve and column. The 0.75 mm bore versions are suitable for higher flow rates in semi-prep systems or for solvent supply from pump to autosampler.

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