CUSTOM ITEM: Guard Column Holder Nut, PEEK, for 3.0 mm ID Guard Columns with 8 mm active length. ARE-Applied Research brand. Bulk Price.
Additional Info:
The 49330‑GC3 All‑PEEK Guard Column Holder Nut is a replacement fastening component designed for use with 3.0 mm ID guard column systems with 8 mm active length cartridges. This part secures the guard column cartridge within the holder, ensuring leak-free operation and proper system alignment.
⚠️ This is a replacement component only and not a complete guard column kit or cartridge.
Manufactured from extruded PEEK (polyether ether ketone), this holder nut maintains a 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 contact with metal components is critical.
✅ Component Function & Benefits
Replacement Guard Column Holder Nut Secures cartridge within the guard column holder assembly
Supports Leak-Free Operation Maintains proper compression and sealing of frits and cartridge
True Bioinert Construction Eliminates metal exposure in wetted system interfaces
Durable & Chemically Resistant Suitable for repeated use in demanding HPLC conditions
Performance & Design
This holder nut is manufactured from extruded PEEK, providing:
High mechanical strength and durability
Chemical resistance across a wide range of mobile phases
Compatibility with bioinert chromatography systems
Carbon is incorporated into the PEEK prior to extrusion, resulting in a durable black finish without altering the inherent chemical properties of the material.
