Filson Polypropylene Frits

Efficient Polypropylene Frits Serving the World

Filson fabricates frits from quality, chromatographic-grade polypropylene material for the best performance of column system. We offer a wide range of sizes to fit most columns and fully support your business.

To get a correct frit, you should check its pore size compatibility with the particle size of the packing in the column. If the packing has a smaller particle size than the pore size of the frit, the packing may clog the frit which leads to the low efficiency.

Usually, you should customize the pore size of Filson polypropylene frit slightly smaller than the packing particle size. For example, if your packing particle size is about 3 or 4 micron, then you are supposed to use a 0.5 micron PP frit, and for 5 – 20 micron packing, a 2 micron frit is recommended.

Filson PP frits are versatile to be used in the most challenging chromatography applications. Choose Filson and do more with a powerful frit.
