Service Manual Cobas Integra 400 Plus -

The Cobas Integra 400 Plus is a computer-controlled analyzer that uses a combination of photometric and immunoturbidimetric measurement techniques. The instrument consists of several modules, including a sample handler, reagent handler, and a measurement module. The analyzer can perform a wide range of tests, including routine clinical chemistry tests, such as glucose, cholesterol, and electrolytes, as well as specialized tests, such as therapeutic drug monitoring and immunosuppressant testing.

The analyzer processes human serum, plasma, and urine. Technicians must wear appropriate Personal Protective Equipment (PPE)—including lab coats, gloves, and protective eyewear—whenever opening the main housing doors.

: Service personnel should verify the TAS version file (e.g., in C:/ickv22XX or C:/ickv33XX depending on the SW version) to ensure the correct configuration files are loaded. Routine Operation & Daily Maintenance

Before servicing or relocating the unit, engineers must verify that the laboratory environment meets the manufacturer’s technical specifications. Requirement Parameter Specification Metric 100–240 V AC ( ), 50/60 Hz, single phase Power Consumption Maximum 1200 VA Ambient Temperature 15°C to 32°C (Fluctuations must not exceed Service Manual Cobas Integra 400 Plus

). The manual includes specific procedures for ISE calibration and electrode replacement. 4. Preventive Maintenance Procedures

The is a precision instrument. Attempting to repair it without the official service manual is akin to navigating a submarine without a sonar map—you might move, but you will eventually crash. For labs and service companies, the cost of a service contract or certified training is marginal compared to the cost of a single major component failure (e.g., a photometer unit priced at over $5,000).

The Cobas Integra 400 Plus is a highly reliable, automated biochemistry analyzer designed for clinical laboratories with low-to-medium sample volumes. Manufactured by Roche Diagnostics, this system integrates multiple analytical technologies into a single compact desktop unit.

The Cobas Integra 400 Plus integrates four processing technologies into a single compact desktop platform: photometry, fluorescence polarization, turbidimetry, and ion-selective electrode (ISE) potentiometry. Key Technical Specifications Up to 400 tests per hour (including ISE). The analyzer processes human serum, plasma, and urine

An authorized for the Cobas Integra 400 Plus is structured to guide technicians through installation, preventive maintenance, repair, and troubleshooting. Key sections generally include:

The manual mandates specific cleaning materials; using organic solutions can damage plastic components like cuvettes. Technicians are often instructed to use a 70% propanol solution for external surfaces.

The Cobas Integra 400 Plus integrates reagent handling, sample processing, incubation, and photometric detection into an automated workflow. Its modular architecture allows for routine assays across multiple test panels and supports random-access testing to prioritize urgent samples. The instrument’s design emphasizes reproducibility, operator safety, and ease of reagent and consumable exchange.

), the ISE module requires distinct maintenance. The manual illustrates the construction of the ISE tower, the peristaltic pumps dedicated to calibrators, and the reference electrode pathways. Troubleshooting and Error Code Analysis
