HPLC Column Set, PEEK with a 4.6 mm ID. Includes, a 150 mm x 4.6 mm black, column body tube (1/2-20 threads), plus 2 PEEK 2 um frits & 2 end fittings. ARE-Applied Research brand. 1 EA.
Additional Info:
The 49335‑150 All‑PEEK HPLC Column Set is designed for professional column packers and advanced chromatographers who require maximum control over bioinert column construction. The 150 mm length configuration is ideal for high-resolution analytical separations where enhanced peak capacity and separation efficiency are critical.
PEEK (polyether ether ketone) column hardware provides a completely metal‑free flow path, eliminating unwanted interactions with stainless steel that can affect sensitive analytes. This makes it the preferred solution for proteins, peptides, nucleic acids, ions, and metal‑sensitive small molecules, ensuring improved recovery and reproducibility.
✅ Why Choose All‑PEEK Column Hardware
True Bioinert Flow Path Eliminates metal interactions for sensitive compounds
Improved Recovery & Peak Shape Minimizes adsorption and secondary surface effects
Pack Any Stationary Phase Full flexibility for custom column development
Reusable & Repackable Design Supports method development and optimization workflows
Standard 1/2‑20 Thread Format Compatible with common 4.6 mm HPLC packing systems
Performance & Design
The column body is manufactured using a proprietary extrusion process that produces a smooth, mirror‑like internal surface, enabling:
Highly consistent packing
Reduced flow path disruption
Improved chromatographic efficiency
The material is graphite-filled PEEK, where graphite is incorporated during extrusion, not applied afterward.
Key advantages:
No chemical coatings or surface treatments
Uniform internal chemistry for reproducibility
Durable black finish that maintains appearance over time
