Filson PTFE Frits

Professional PTFE Frits Exporting to the Whole World

Filson designs and manufactures PTFE frits in different dimensions and micon ratings to comply with customer specific needs. At this time, the right selection of the product for the column system seems quite important and little difficult.

To ensure that the right Filson PTFE frit is selected, make sure that the aperture of the frit matches the aperture of the packing inside the column. Problems can occur if large aperture frits are used in conjunction with small particle size packing. This combination can lead to packing leakage or frit clogging, which can shorten column life or damage the flow cell.

Filson PTFE frits can be made as thin as you want. And the diameter of the frit is ranging from 0.064 inch to 1 inch to perfectly suit your column. Using a proper PTFE frit will lower the possibility of column damage and bring the better column efficiency.
