CUSTOM ITEM: Frit, PEEK, 2 um, for use with the 4.6 mm All-PEEK column HPLC columns. EPP-Porous Products brand. Bulk Price.
Additional Info:
The 49331‑F5‑2 PEEK Frit is a precision porous retention component designed for use in 4.6 mm ID All‑PEEK HPLC column hardware systems. Featuring a 2 µm pore size, this frit ensures effective particle retention and uniform solvent distribution, supporting high-efficiency analytical separations.
Manufactured entirely from PEEK (polyether ether ketone), this frit provides a fully bioinert, metal‑free flow path, making it ideal for proteins, peptides, nucleic acids, ions, and other metal‑sensitive analytes.
In addition to column packing applications, this frit can also be used as an inline filtration component, offering flexibility in custom fluidic configurations.
✅ Key Benefits
2 µm Porosity for Fine Particle Retention Suitable for sub‑3 µm and high-efficiency analytical stationary phases
True Bioinert Construction (All‑PEEK) Eliminates metal interaction and preserves analyte integrity
Dual Use: Column Packing & Inline Filtration Supports both packed column systems and external filtration setups
These All-PEEK frits are made for use with the ARE-Applied Research Brand, All-PEEK, 4.6mm ID, HPLC Column Hardware or as inline filters and are compatible with 49681-TF-005 and 49681-TF-010
