Guard Column Cartridge, PEEK, 3.0 mm ID, 8mm active length. Frits sold separately. ARE-Applied Research brand. 5/PK.
Additional Info:
The 49330‑GC2‑005 All‑PEEK Guard Column Cartridges are replacement guard column tube components designed for use with compatible PEEK guard column holder systems. Supplied in a 5/pack configuration, these cartridges support high-throughput laboratories and routine maintenance workflows.
⚠️ This product is a component only and not a complete kit. Frits and holder are sold separately.
Constructed from extruded PEEK (polyether ether ketone), these cartridges provide a fully metal‑free, bioinert flow path, eliminating unwanted interactions between analytes and stainless steel surfaces. This is critical for proteins, peptides, nucleic acids, ions, and metal‑sensitive compounds, where adsorption or catalytic effects can reduce recovery and affect chromatographic accuracy.
✅ Component Function & Benefits
Bulk Pack of Replacement Cartridges (5/PK) Ideal for high-throughput workflows and routine maintenance
True Bioinert Flow Path Eliminates metal interaction for sensitive analytes
Protects Analytical Columns Helps reduce contamination and extend column lifetime
Flexible Configuration Allows selection of frit type and porosity based on application needs
Performance & Design

Minimal band broadening
Low dispersion
Consistent flow characteristics
Made entirely from extruded PEEK, these cartridges offer:
No chemical coatings or surface treatments
Uniform internal surface chemistry
Reliable, reproducible bioinert performance
