Upchurch Scientific® Stainless Steel frits are available in several porosities: 0.5, 2, 10, and 20 µm. Most of these frits include either a PCTFE, ETFE or PEEK polymer sealing ring and many have the common 0.250”(0.64 cm) and 0.254"(0.64 cm) OD's, which allow them to be used in Upchurch Scientific® precolumn and inline filters. Choose frits with larger diameter faces and/or larger porosities for faster flow rates. Smaller diameter faces and/or smaller porosities are ideal for applications sensitive to extra flow path volume.
