Solving the Discontinued Hardware Crisis

GE Healthcare transitioned its life science division to Cytiva in 2020. With that transition came the formal end-of-life for a range of legacy ÄKTA control hardware, including the CU950. Cytiva's current portfolio does not offer a backward-compatible drop-in replacement for this unit. Facilities running ÄKTA systems built around the CU950 architecture face a hard reality: the control unit is the operational core of the instrument. Without it, columns sit idle, purification runs stop, and batch production halts.

For bioprocessing facilities operating under FDA 21 CFR Part 11, EU GMP Annex 11, or equivalent regulatory frameworks, the CU950 is not simply a piece of hardware — it is a validated component within a qualified system. Introducing a new control platform requires a full IQ/OQ/PQ cycle, updated validation documentation, and in many cases, regulatory notification. The cost and timeline of that process make sourcing a like-for-like CU950 replacement the only operationally rational decision for most facilities.

Extending the operational life of an ÄKTA system by 5 to 10 years through strategic spare part procurement is a documented and defensible asset management strategy. A single CU950 unit held in reserve eliminates the single point of failure that would otherwise force a platform decision under emergency conditions — the worst possible context in which to make a capital investment of that magnitude.

Condition & Reliability Assurance

Every CU950 unit processed through DriveKNMS undergoes a structured 5-step quality assessment before it is offered for sale:

• Step 1 – Electrolytic Capacitor Inspection: Aging electrolytic capacitors are the primary failure mode in legacy control electronics. Each unit is inspected for capacitor bulging, leakage, and ESR degradation. Units with compromised capacitors are either recapped or removed from inventory.
• Step 2 – Firmware Version Verification: The installed firmware version is confirmed and documented. Compatibility with the target ÄKTA system configuration is verified prior to dispatch.
• Step 3 – Pin and Connector Corrosion Audit: All interface connectors, backplane pins, and board-level contacts are inspected under magnification for oxidation, corrosion, and mechanical damage. Affected contacts are cleaned or the unit is rejected.
• Step 4 – Functional Bench Test: Where test infrastructure permits, units are powered and subjected to functional verification against known-good reference parameters.
• Step 5 – Packaging and ESD Protection: Units are packed in anti-static shielding with appropriate cushioning for international freight. Condition grade and test results are documented and shipped with the unit.
