HPLC Column Set, PEEK with a 2.1 mm ID. Includes, a 100 mm x 2.1 mm black, column body tube (1/4-28 threads), plus 2 PEEK 2 um frits & 2 end fittings. ARE-Applied Research brand. 1 EA.
Additional Info:
The 49334‑100 All‑PEEK HPLC Column Set is designed for professional column packers and LC‑MS users who require maximum control over bioinert column construction in a high-efficiency, low-flow format. This 2.1 mm ID hardware set enables in‑house packing of custom HPLC and LC‑MS columns using virtually any stationary phase.
Constructed entirely from PEEK (polyether ether ketone), this column provides a completely metal‑free flow path, helping eliminate 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 recovery and chromatographic performance.
✅ Why Choose All‑PEEK Column Hardware
True Bioinert Flow Path Eliminates metal contact to protect sensitive analytes
Improved Recovery & Peak Integrity Reduces adsorption and unwanted secondary interactions
Pack Any Stationary Phase Full flexibility for custom separations and advanced method development
Reusable & Repackable Design Ideal for LC‑MS workflows and method optimization
Optimized for 2.1 mm Low‑Flow Systems (1/4‑28 Threads) Supports efficient, solvent-saving analytical methods
Performance & Design
The column body is manufactured from extruded PEEK tubing using a proprietary process that produces a smooth, mirror-like inner surface, helping to:
Improve packing consistency
Reduce flow disruption and eddy diffusion
Enhance chromatographic efficiency and resolution
Unlike coated or treated hardware, this column is:
Not chemically modified
Not surface coated
Inherently bioinert through material composition
A controlled amount of graphite is incorporated into the PEEK before extrusion, creating the black finish that enhances durability while maintaining structural stability.

⚠️ When to Use PEEK Column Hardware
Choose All‑PEEK columns when:
Samples may adsorb to or react with metal surfaces
High recovery and reproducibility are critical
Working with biomolecules or coordination-sensitive analytes
A fully bioinert LC or LC‑MS system is required
Packing & Compatibility
For optimal results:
Use with All‑PEEK Slurry Reservoir Kits designed for longer 2.1 mm columns
Select frit porosity based on particle size
Maintain a fully bioinert packing and flow path environment
