Clean the wash blocks and aspiration needles to prevent carryover contamination. Bi-Annual and Annual Technical Service
The most legitimate and reliable path to obtaining the full Service Manual is through Roche Diagnostics directly. Access is typically granted to or as part of an annual service contract . Many users on platforms like MedWrench are actively seeking these PDFs for unsupported or second-hand units, highlighting the difficulty of finding "abandonware" versions online.
Inconsistent electrolyte readings or slope failures during ISE calibration.
Solution: Replace the affected cuvette segment and rerun the water blank calibration. Fluidic and Pipetting Errors Service Manual Cobas Integra 400 Plus
Always wear appropriate personal protective equipment (PPE), including gloves and lab coats, when servicing the fluidics or probe assemblies. The instrument processes human blood and bodily fluids capable of transmitting bloodborne pathogens.
