HPLC Column Set, PEEK with a 7.5 mm ID. Includes, a 30 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 49333‑30 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 enables increased loading capacity and throughput, while maintaining a completely metal‑free flow path.
PEEK (polyether ether ketone) column hardware eliminates unwanted interactions between analytes and stainless steel, making it ideal for proteins, peptides, nucleic acids, ions, and metal‑sensitive compounds, where recovery and reproducibility are critical.
✅ Why Choose All‑PEEK Column Hardware
True Bioinert Flow Path Prevents metal interaction with sensitive analytes
Higher Sample Loading Capacity (7.5 mm ID) Supports semi‑preparative and scale‑up applications
Improved Recovery & Peak Integrity Minimizes adsorption and secondary interactions
Pack Any Stationary Phase Full control over custom column packing
Reusable & Repackable Design Ideal for method development, scale‑up, and process optimization
Performance & Design
The column body is manufactured from extruded PEEK tubing using a proprietary process that creates a smooth, mirror‑like internal surface, supporting:
Uniform and reproducible packing
Reduced flow path disruption
Improved separation performance
This column is constructed from graphite-filled PEEK, where graphite is added prior to extrusion, not applied as a coating.
Key advantages:
No chemical coatings or treatments
Consistent internal chemistry
Durable black exterior for extended use
