CUSTOM ITEM: Guard Column Holder Insert, PEEK, for 3.0 mm ID Guard Columns with 8 mm active length. ARE-Applied Research brand. Bulk Price.
Additional Info:
The 49330‑GC4 All‑PEEK Guard Column Holder Insert is a replacement internal component designed for use with 3.0 mm ID guard column systems featuring 8 mm active length cartridges. This part fits inside the guard column holder assembly, helping ensure proper alignment, sealing, and flow path integrity.
⚠️ This is a replacement component only and not a complete guard column kit or cartridge.
Manufactured from extruded PEEK (polyether ether ketone), this insert maintains a fully bioinert, metal‑free interface, supporting sensitive analytical workflows. It is ideal for applications involving proteins, peptides, nucleic acids, ions, and metal‑sensitive compounds, where minimizing interaction with metallic surfaces is essential for performance and reproducibility.
