HPLC Column Set, PEEK with a 4.6 mm ID. Includes, a 50 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 49335‑05 All‑PEEK HPLC Column Set is designed for professional column packers and advanced chromatographers who require complete control over bioinert column construction. This 4.6 mm ID hardware set enables in‑house packing of custom HPLC columns using virtually any stationary phase.
PEEK (polyether ether ketone) column hardware provides a fully metal‑free flow path, helping prevent undesirable interactions between analytes and stainless steel surfaces. This is critical for proteins, peptides, nucleic acids, ions, and metal‑sensitive small molecules, where adsorption or catalytic effects can compromise results.
✅ Why Choose All‑PEEK Column Hardware
True Bioinert Flow Path Eliminates metal contact to protect sensitive analytes
Improved Recovery & Peak Integrity Reduces adsorption and secondary interactions common with stainless steel columns.
Pack Any Stationary Phase Full flexibility for method development and custom separations
Reusable & Repackable Design Ideal for R&D, method optimization, and specialized workflows
Compatible with Standard Packing Systems Uses 1/2‑20 threaded format for 4.6 mm ID columns
Performance & Design
The column body is manufactured from extruded PEEK tubing using a proprietary process that creates a smooth, mirror‑like inner surface. This highly uniform internal bore helps:
Improve packing consistency
Reduce flow disruption
Enhance chromatographic efficiency
Unlike coated or treated hardware, this column is:
Not chemically modified
Not surface coated
Fully inherent in its bioinert properties
A controlled amount of graphite is incorporated into the PEEK prior to extrusion, producing the durable black finish while maintaining structural integrity and long-term usability.
