Guard Column Holder Nut, PEEK, for 3.0 mm ID Guard Columns with 8 mm active length. ARE-Applied Research brand. 5/PK.
Additional Info:
The 49330‑GC3‑005 All‑PEEK Guard Column Holder Nuts are replacement fastening components designed for 3.0 mm ID guard column systems with 8 mm active length cartridges. Supplied in a 5/pack configuration, these components are ideal for routine maintenance and high‑throughput laboratory environments.
⚠️ 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 holder nuts maintain a bioinert, metal‑free interface, ensuring compatibility with sensitive analytical workflows. They are well suited for proteins, peptides, nucleic acids, ions, and metal‑sensitive compounds, where minimizing metal exposure is essential for accurate and reproducible results.
✅ Component Function & Benefits
Bulk Pack of Replacement Holder Nuts (5/PK) Supports routine maintenance and reduces downtime
Secure Cartridge Retention Ensures proper compression and leak-free sealing
True Bioinert Construction Maintains metal‑free interfaces for sensitive workflows
Durable & Chemically Resistant Designed for repeated use in demanding HPLC applications
Performance & Design
Each holder nut is manufactured from extruded PEEK, providing:
High mechanical strength
Excellent chemical resistance
Reliable long-term performance
Carbon is incorporated into the PEEK prior to extrusion, producing a durable black finish without altering the inherent chemical properties or bioinert behavior of the material.
