Frits are filters made of glass or ceramics, which are used to filter even the finest particles and are among the most frequently used filters in HPLC systems. They are available in various porosities and sizes, and are thus suitable for many applications. The porous parts of the frits come with different diameters and porosities. Depending on your flow rate, you may want to use a larger "filtering face" to achieve good filtering with lower back pressure. PEEK frits are inert, biocompatible and are suitable for a wide range of low and high pressure applications.
We offer frits from Agilent Technologies, Merck Millipore, Restek, SGE, Supelco, Upchurch Scientific, Vici Jour, Vici Valco und Waters.
