What is a Frit?

A frit is a porous metallic or polymeric material, usually formed into a disc shape. A frit is designed to prevent the passage of particulate matter while allowing fluid to flow through it. Two common uses of a frit is as an inline solvent filter and to contain the packing material inside a column tube. Frits vary in porosity from 0.5µm (used as inline filters for protecting an HPLC column) to 20µm (used for large particulate filtration in high-flow systems).
