Stainless Steel Frits - PEEK-Encased Type

PEEK-encased stainless steel frits
  • For HPLC columns or in-line filters
  • Eliminate poorly swept volume and improves peak symmetry
  • Various porosities and dimensions available

Our PEEK-encased frits with 0.115" or 1/4" OD ring are intended for HPLC columns with IDs of 3.2, 3.9, and 4.6 mm. With the frit surrounded by a PEEK ring, the actual porous surface is reduced to the column ID.

The compressed PEEK ring forms a seal between the bottom of the fitting and the column end, preventing the mobile phase and the sample from entering the previously accessible poorly swept areas.
