HPLC Column Set, PEEK with a 7.5 mm ID. Includes, a 50 mm x 7.5 mm black, column body tube (5/8-18 threads), plus 2 PEEK 5 um frits, 2 frit spacers & 2 end fittings. ARE-Applied Research brand. 1 EA.
Additional Info:
The 49333‑50 All‑PEEK HPLC Column Set is designed for professional column packers and preparative chromatographers who require bioinert, higher‑capacity column hardware for semi‑preparative separations. The 7.5 mm ID format increases sample loading capacity and throughput, while maintaining a completely metal‑free flow path.
PEEK (polyether ether ketone) column hardware eliminates interactions with stainless steel surfaces, making it ideal for proteins, peptides, nucleic acids, ions, and metal‑sensitive small molecules, where adsorption or catalytic effects can reduce recovery and affect chromatographic accuracy.
✅ Why Choose All‑PEEK Column Hardware
True Bioinert Flow Path Prevents analyte interaction with metal surfaces
Higher Sample Loading Capacity (7.5 mm ID) Supports semi‑prep and scale‑up workflows
Improved Recovery & Peak Integrity Minimizes adsorption and secondary interactions
Pack Any Stationary Phase Complete flexibility for custom column development
Reusable & Repackable Design Ideal for method development and process scale‑up
Performance & Design
The column body is produced using a proprietary extrusion process that creates a smooth, mirror‑like internal surface, enabling:
Uniform and reproducible packing
Reduced flow disruption
Improved chromatographic efficiency
Constructed from graphite-filled PEEK, the graphite is incorporated before extrusion, not applied as a coating.
Key advantages:
No chemical coatings or surface treatments
Consistent internal surface chemistry
Durable black exterior for long-term use
