GE Cytiva Accessory Kit for HiScale 26 Column

Cytiva 28-9663-74 Accessory Kit for HiScale 26 Column (Partial Kit)

The Cytiva (formerly GE Healthcare) 28-9663-74 is an accessory and maintenance kit designed specifically for the HiScale 26 series of preparative chromatography columns. HiScale columns are engineered for high-pressure, high-resolution protein purification, and maintaining their fluidic seals is critical for reproducible results. Please note: This is a PARTIAL KIT. It includes essential sealing and connection components—specifically 1 net ring, 1 O-ring, 1 ferrule, and 2 fingertight stop plugs—but does not include the mesh support screen. This partial kit is an ideal, cost-effective solution for laboratories that need to replace lost storage plugs, worn O-rings, or damaged tubing ferrules without purchasing a complete column rebuild set.

Included Components and Design

• O-Ring & Net Ring (1 each): Essential for maintaining a leak-proof seal between the column tube and the adapter assembly, preventing pressure drops and sample leakage during high-flow FPLC runs.

• Fingertight Stop Plugs (2 included): Used to securely cap the fluidic inlet and outlet of the column during storage. This ensures the packed chromatography resin remains hydrated in its storage buffer (typically 20% ethanol) and prevents microbial contamination.

• Ferrule (1 included): Slips over standard capillary tubing to provide a secure, high-pressure grip when connecting the HiScale column to chromatography systems such as the AKTA pure or AKTA avant.

• Missing Component: Mesh support screen is NOT included in this specific lot.

Product Specifications

• Catalog Number: 28-9663-74 (28966374)

• System Compatibility: Cytiva / GE HiScale 26 Chromatography Columns

• Kit Status: Partial / Incomplete

• Included Parts: (1) Net Ring, (1) O-Ring, (1) Ferrule, (2) Stop Plugs

Key Benefits & Applications

• Routine Column Maintenance: O-rings flatten and degrade over time due to compression and chemical exposure. This kit provides the OEM replacement to restore optimal column pressure limits.

• FPLC Integration: The included ferrule ensures a zero-dead-volume connection to the system valves, minimizing band broadening and sample dilution.

• Secure Column Storage: The two stop plugs allow researchers to safely disconnect a packed column from the system and store it in a cold room without fear of the bed drying out.

Partial Kit - 1 net ring, 1 o-ring, 1 ferrule, and 2 fingertight stop plugs only. Does not include mesh support screen.
