Replace the photometer light source if the lamp voltage falls below the specified threshold or hits its maximum operational hours (typically 1,000–2,000 hours).
Disconnect the primary power source before opening the electronic housing panels or replacing circuit boards.
Clean the sample and reagent rotors with specialized decontaminating solutions. Clean the ISE cell and perform an ISE rinse sequence.
The Cobas Integra 400 Plus is a laboratory analyzer designed for clinical chemistry and immunoassay testing. As a widely used instrument in medical laboratories, it is essential to have a comprehensive service manual that provides detailed information on its operation, maintenance, and troubleshooting. Here, we will provide an essay on the service manual for the Cobas Integra 400 Plus. Always wear gloves, lab coats, and safety goggles
The Cobas Integra 400 Plus utilizes a combination of four measurement technologies: photometry, turbidimetry, fluorescence polarization immunoassay (FPIA), and ion-selective electrode (ISE) potentiometry. Understanding its physical layout is crucial for any servicing or calibration task. Key Hardware Modules
Cobas Integra 400 Plus is a fully automated, tabletop clinical chemistry analyzer designed for laboratories with a moderate throughput (roughly 50 to 250 samples per day). Efficient maintenance and service of this unit are critical for ensuring high-precision results and reducing downtime. Diamond Diagnostics Core Components & Specifications The system integrates four measurement principles: absorbance photometry turbidimetry fluorescence polarimetry ion-selective electrode (ISE) potentiometry Block Scientific Throughput: Up to 400 tests per hour.
