Guard Column Holder Insert, PEEK, for 3.0 mm ID Guard Columns with 8 mm active length. ARE-Applied Research brand. 5/PK.
Additional Info:
The 49330‑GC4‑005 All‑PEEK Guard Column Holder Inserts are replacement internal components designed for 3.0 mm ID guard column systems with 8 mm active length cartridges. Supplied in a 5/pack configuration, these inserts are ideal for routine maintenance and high‑throughput laboratory environments requiring reliable, consistent performance.
⚠️ This product is a replacement hardware component only and not a complete guard column kit or cartridge.
Manufactured from extruded PEEK (polyether ether ketone), these inserts maintain a fully bioinert, metal‑free interface, ensuring compatibility with sensitive analytical workflows. They are especially suitable for proteins, peptides, nucleic acids, ions, and metal‑sensitive compounds, where eliminating metal contact is essential for accuracy and reproducibility.
