HPLC Column Set, PEEK with a 7.5 mm ID. Includes, a 150 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 49333‑150 All‑PEEK HPLC Column Set is designed for professional column packers and preparative chromatographers who require high‑capacity, bioinert column hardware for semi‑preparative separations and purification workflows. The 7.5 mm ID provides increased loading capacity, while the 150 mm length delivers enhanced resolution and improved separation efficiency for more complex mixtures.
PEEK (polyether ether ketone) column hardware provides a completely metal‑free flow path, eliminating unwanted interactions that can occur with stainless steel. This makes it ideal for proteins, peptides, nucleic acids, ions, and metal‑sensitive small molecules, where adsorption or catalytic effects can impact recovery and chromatographic performance.
✅ Why Choose All‑PEEK Column Hardware
True Bioinert Flow Path Eliminates interaction with metal surfaces
Higher Sample Loading Capacity (7.5 mm ID) Supports semi‑preparative purification and scale‑up
Improved Recovery & Peak Shape Minimizes adsorption and secondary effects
Pack Any Stationary Phase Full flexibility for custom separations
Reusable & Repackable Design Ideal for method development and purification workflows
Performance & Design
The column body is manufactured using a proprietary extrusion process that produces a smooth, mirror‑like internal surface, enabling:
Uniform and reproducible packing
Reduced turbulence in the flow path
Improved chromatographic efficiency
Constructed from graphite-filled PEEK, the graphite is incorporated before extrusion, ensuring consistent material properties without surface treatment.
Key advantages:
No coatings or chemical surface treatments
Uniform internal surface chemistry
Durable black outer finish for long-term use
