Stainless steel frits

Product / Chromatography

The analytical-scale 316 stainless steel frits come in 0.5 and 2 µm porosity, the most common filtration ratings in HPLC, each with a PCTFE or PEEK polymer sealing ring. For semi-preparative flow rates, porosities of 2, 5, 10 and 20 µm and a range of diameters are offered (PCTFE, ETFE or PTFE ring). Many have the common 0.250" (6.35 mm) and 0.254" (6.45 mm) ODs and fit many guard column, precolumn and inline filter housings. Faster flow rates may require larger filtration area and/or larger porosity.
