CUSTOM ITEM: End Fitting, PEEK, for 7.5 mm ID columns, ARE-Applied Research brand. Bulk Price.
Additional Info:
The 49333‑EF7 PEEK End Fitting is a precision-machined connection component designed specifically for 7.5 mm ID All‑PEEK HPLC column hardware systems. This fitting provides the critical interface between HPLC tubing and semi‑preparative column bodies, ensuring secure, leak‑free operation and consistent chromatographic performance.
This end fitting features a dual-thread configuration:
10‑32 female thread (tubing inlet)
5/8‑18 column thread (column body connection)
Manufactured from high-performance PEEK (polyether ether ketone), this component provides a fully bioinert, metal‑free flow path, making it ideal for proteins, peptides, nucleic acids, ions, and metal‑sensitive compounds.
