Frit, PEEK-Encased Stainless Steel, 0.5 µm, 1/4" Diam. x 0.062" Thick, 5/pk

Frits are surrounded with a ring of PEEK to reduce the actual porous surface to the ID of an HPLC column. 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.

PEEK-encased frits with 0.115" or 1/4" OD rings are intended for HPLC columns with IDs of 2.0, 3.2, 3.9, and 4.6 mm.

Note:  Stated frit porosities are only nominal and do not reflect the maximum pore size of a frit.
