CUSTOM ITEM: Guard Column Cartridge, PEEK, 3.0 mm ID, 8mm active length. Frits sold separately. ARE-Applied Research brand. Bulk Price.
Additional Info:
The 49330‑GC2 All‑PEEK Guard Column Cartridge is a replacement guard column tube component designed for use with compatible PEEK guard column holder systems. This cartridge provides a metal‑free, bioinert flow path for protecting analytical columns in demanding workflows.
⚠️ This is a component only and not a complete kit. Frits and holder are sold separately.
Constructed entirely from extruded PEEK (polyether ether ketone), this guard column cartridge eliminates unwanted interactions between analytes and stainless steel surfaces. It is ideal for proteins, peptides, nucleic acids, ions, and metal‑sensitive compounds, where adsorption or catalytic effects can negatively impact recovery and chromatographic performance.
