HPLC Column Set, PEEK with a 7.5 mm ID. Includes, a 100 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 49333‑100 All‑PEEK HPLC Column Set is designed for professional column packers and preparative chromatographers who require bioinert, high‑capacity column hardware for semi‑preparative and scale‑up separations. The 7.5 mm ID format increases sample loading capacity, while the 100 mm length provides enhanced resolution and separation efficiency for more demanding applications.
PEEK (polyether ether ketone) column hardware provides a fully metal‑free flow path, eliminating interactions with stainless steel that can affect sensitive compounds. This makes it ideal for proteins, peptides, nucleic acids, ions, and metal‑sensitive small molecules, where recovery, accuracy, and reproducibility are critical.
✅ Why Choose All‑PEEK Column Hardware
True Bioinert Flow Path Prevents interaction with metal surfaces
Higher Sample Loading Capacity (7.5 mm ID) Supports semi‑prep and scale‑up workflows
Improved Recovery & Peak Shape Minimizes adsorption and secondary interactions
Pack Any Stationary Phase Complete flexibility for custom column packing
Reusable & Repackable Design Ideal for process development and optimization
Performance & Design
The column body is manufactured using a proprietary extrusion process that produces a smooth, mirror‑like internal surface, supporting:
Consistent 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 treatments
Uniform internal surface chemistry
Durable black exterior for long-term use
