Guard Column Holder Nut, PEEK, for 3.0 mm ID Guard Columns with 8 mm active length. ARE-Applied Research brand. 10/PK.
Additional Info:
The 49330‑GC3‑010 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 10/pack configuration, these components are ideal for high-throughput laboratories and routine maintenance workflows requiring consistent, reliable 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 holder nuts maintain a bioinert, metal‑free interface, ensuring compatibility with sensitive analytical workflows. They are particularly useful for proteins, peptides, nucleic acids, ions, and metal‑sensitive compounds, where minimizing metal exposure is critical for accurate, reproducible results.
✅ Component Function & Benefits
Bulk Pack of Replacement Holder Nuts (10/PK) Supports high-throughput workflows and reduces maintenance downtime
Secure Cartridge Retention Ensures proper compression and leak-free operation
True Bioinert Construction Maintains a metal‑free system interface
Durable & Chemically Resistant Designed for repeated use under demanding HPLC conditions
Performance & Design
Each holder nut is manufactured from extruded PEEK, providing:
High mechanical strength and durability
Broad chemical compatibility with common mobile phases
Long-term reliability in analytical workflows
Carbon is incorporated into the PEEK prior to extrusion, producing a durable black finish without altering the chemical or bioinert properties of the material.
