End Fitting, PEEK, for 4.6 mm ID columns, ARE-Applied Research brand. 10/PK.
Additional Info:
The 49333‑EF4‑010 PEEK End Fittings are precision-machined column connection components designed for 4.6 mm ID All‑PEEK HPLC column hardware systems. Supplied in a 10/pack configuration, these fittings are ideal for high-throughput column packing, system builds, and routine maintenance workflows.
Each end fitting provides the critical interface between HPLC tubing and the column body, featuring:
10‑32 female inlet thread (standard HPLC tubing connection)
1/2‑20 column thread (column body connection)
Manufactured from high-performance PEEK (polyether ether ketone), these fittings maintain a fully bioinert, metal‑free flow path, making them ideal for proteins, peptides, nucleic acids, ions, and metal‑sensitive analytes.
✅ Key Benefits
Essential Column Connection Component Critical interface between tubing and 4.6 mm ID column bodies
True Bioinert Flow Path (PEEK Construction) Eliminates metal interaction and preserves analyte integrity
Low Dead‑Volume Interface Minimizes dispersion and maintains peak performance
Bulk Pack (10/PK) for High‑Throughput Workflows Reduces downtime and supports continuous operations
Standard Thread Compatibility 10‑32 tubing inlet and 1/2‑20 column connection
