GE AKTA CU950 Controller – Bioprocess Chromatography Automation Control Unit | AKTA Series Platform
Engineering Background: The GE AKTA CU950 is a dedicated control unit engineered for the AKTA family of liquid chromatography and bioprocess purification systems. Developed by GE Healthcare Life Sciences (now Cytiva), the CU950 serves as the central automation brain coordinating pump control, UV/conductivity monitoring, fraction collection, and system interlocks across AKTA Explorer, AKTA Purifier, and compatible platform configurations.
Product Positioning: Designed for procurement engineers and lab automation specialists sourcing replacement or expansion control hardware for established AKTA installations. The CU950 eliminates the need for full system replacement when the control unit fails, offering a cost-effective path to restoring validated bioprocess workflows. Konmask.com supplies verified surplus and refurbished CU950 units with full functional inspection.

System Architecture & Signal Flow
The CU950 operates as the master controller within the AKTA system bus architecture. It receives sensor inputs (UV absorbance, conductivity, pH, pressure) from inline detectors and issues command signals to pumps, valves, and fraction collectors via the AKTA proprietary communication bus. The UNICORN software interface communicates with the CU950 over a serial connection, enabling real-time method control, alarm management, and data acquisition. Signal flow is unidirectional from UNICORN → CU950 → field devices, with status feedback looped back to the software layer for display and logging.

Technical FAQ
Q: Is the CU950 compatible with UNICORN 7.x and later versions?
A: Compatibility depends on the specific AKTA system configuration. We recommend confirming your UNICORN version and AKTA system model before ordering. Contact us for compatibility verification.
Q: Can the CU950 be used as a standalone controller without a full AKTA system?
A: No. The CU950 is designed to operate within the AKTA system bus and requires the full system wiring harness and UNICORN software for functional operation.
Q: Do you provide a certificate of conformance or test report?
A: A functional test confirmation document is available upon request. Full OEM calibration certificates are not available for surplus units.
Q: What is the lead time for international shipments?
A: Standard international transit is 5–10 business days via DHL/FedEx Express. Expedited options available upon request.
Q: Is the unit export-controlled?
A: Bioprocess laboratory equipment is generally not subject to export controls, but buyers are responsible for verifying import regulations in their destination country.
