Upchurch Scientific® PEEK™ frits are suitable for low- and high-pressure applications and offer exceptional uniform porosity to ensure longer filtration life and consistent frit-to-frit swept volumes.

While all Upchurch Scientific® PEEK™ frits are capable of withstanding pressures >5,000 psi (>345 bar), the actual pressure holding capacity of each frit is usually dependent on the filter body in which it is placed.

Upchurch Scientific® Frit-In-A-Ferrule™ seal and filter simultaneously and can filter at any point in your system where ¹/₆ or ¹/₈" Ext.Ø tubing is used in a flat-bottom 1/4-28, M6 or 5/16-24 connection. For more information and a listing of these products, search on 53501-450.

PEEK™ polymer discs are biocompatible, metal free, and inert to most solvents. Disc rings, included on most PEEK™ frits, are made of PCTFE and also also offer excellent chemical resistance. PCTFE surrounded PEEK™ frits can be used up to 80 °C, and PEEK™ frits alone are a good choice for applications up to 100 °C.
