- More Information
Polyethylene frits are a competitively priced biocompatible alternative to titanium and are completely metal-free. Our metal-free polymer frits are made of UHMWPE (Ultra High Molecular Weight Polyethylene).
These frits are surrounded by a ring of PEEK to reduce the actual porous surface to the ID of an HPLC column. The compressed PEEK ring forms a seal between the bottom of the fitting and the column end, preventing the mobile phase and the sample from entering the previously accessible, poorly swept areas.
Stated frit porosities are only nominal and do not reflect the maximum pore size of a frit.
Other dimensions and porosities are available on request. Minimum order quantity depends on dimensions. Please contact your local distributor or VICI Jour directly.
Tolerances: ±0.05 mm (.002")
