PEEK-Encased Stainless Steel Frits

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

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