HPLC Column Set, PEEK with a 4.6 mm ID. Includes, a 100 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 49335‑100 All‑PEEK HPLC Column Set is designed for professional column packers and advanced chromatographers who require full control over bioinert column construction. This 100 mm length configuration is ideal for analytical separations requiring increased resolution and retention.
PEEK (polyether ether ketone) column hardware provides a fully metal‑free flow path, eliminating unwanted interactions that can occur between analytes and stainless steel surfaces. This makes it the preferred choice for proteins, peptides, nucleic acids, ions, and metal‑sensitive small molecules, where adsorption or catalytic effects can negatively impact chromatographic results.
✅ Why Choose All‑PEEK Column Hardware
True Bioinert Flow Path Eliminates metal interaction for sensitive compounds
Improved Recovery & Peak Shape Minimizes adsorption and secondary interactions
Pack Any Stationary Phase Complete flexibility for custom column development
Reusable & Repackable Design Ideal for method development and optimization
Standard 1/2‑20 Thread Format Compatible with common 4.6 mm packing hardware and systems
Performance & Design
The column body is produced using a proprietary extrusion process that results in a smooth, mirror‑like internal surface, supporting:
Consistent and reproducible packing
Reduced flow disruption
Improved separation efficiency
This column is constructed from graphite-filled PEEK, where the graphite is incorporated prior to extrusion, not as a surface treatment.
Key advantages:
No chemical coatings or post‑processing
Uniform internal surface chemistry
Durable black outer finish for long-term handling
