Replacement frits for HPLC columns and column hardware assemblies are used to retain packing material while maintaining controlled flow and pressure stability. This category includes stainless‑steel and titanium frits (filter discs) manufactured for precision chromatography applications, supporting both analytical and preparative workflows.
Consistent frit quality is essential for maintaining column performance, particle retention, and reproducibility during column packing and operation.
Materials & Construction
These frits are manufactured under the EPP‑Porous Products™ brand using high‑purity raw materials and precision sintering processes to ensure:
Controlled and uniform porosity
Reliable mechanical strength
Chemical compatibility with common HPLC solvents
Consistent dimensional tolerances
Available materials include:
Stainless Steel frits, suitable for high‑pressure and rugged applications
Titanium frits, offering enhanced corrosion resistance and bio‑compatibility
Material selection should be based on solvent chemistry, pressure requirements, and analyte sensitivity.
Compatibility & Applications
EPP‑Porous Products™ frits can be used with:
Cogent™ HPLC columns
ARE‑Applied Research™ column hardware
Most standard HPLC column hardware across the market
They are commonly used for:
In‑house column packing and repacking
Replacement of worn or damaged frits
Custom column configurations
OEM and system‑level column hardware assemblies
Porosity & Custom Options
The frits listed in this category represent a sample of existing manufactured sizes and porosities. A wide range of:
