Frit, SS, PEEK enc., 1/4 diam. x 0.062 thickn., 2 um, 5/PAK

Stainless Steel Frits - PEEK-Encased Type. 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.
