Integra 400 Plus — Service Manual Cobas

Most labs have a battered three-ring binder sitting on a shelf near the waste container. Keep it there. While the digital PDF (often found on the Roche DiaLog portal) is searchable, the physical manual has laminated fold-out Pneumatic Diagrams that are impossible to read on a screen. When you have a fluid pressure issue (error 3120-3190), looking at the actual paper map of tubes is faster than zooming on a tablet.

The service manual specifies calibration procedures to establish and verify assay linearity, sensitivity, and accuracy. It defines:

Documented calibration and QC ensure traceability of results and compliance with accreditation standards (e.g., ISO 15189, CLIA).

The cobas integra 400 plus is obsolete enough to be cheap but recent enough to still run routine panels effectively. The Service Manual (Version 4.0 or later) is the difference between a scrapped machine and one that runs for another five years.

Where to find it: Check Roche’s e-Doc portal if you have an active contract. For legacy machines, trade forums like MedWrench or the "Clinical Lab Engineering" Facebook group occasionally have scanned PDFs.

Final Tip: Buy a cheap set of metric hex keys (1.5mm to 5mm) and label them "INTEGRA ONLY." That probe arm does not forgive stripped screws.

The Service Manual for the Cobas Integra 400 Plus is an essential technical document designed for field service engineers and laboratory technicians responsible for the maintenance, repair, and calibration of this automated clinical chemistry analyzer. This manual provides a comprehensive framework for ensuring the system operates at its peak throughput of up to 400 tests per hour. Core Technical Specifications

The manual outlines the physical and functional architecture of the analyzer, which supports four distinct measurement principles: absorbance photometry, turbidimetry, fluorescence polarimetry (FP), and ion-selective potentiometry (ISE).

Dimensions & Utility: The unit measures approximately 135 cm in width, 66 cm in depth, and 75 cm in height, weighing roughly 320 kg.

On-board Capacity: It manages up to 36 different on-board assays, with 32 cassette positions and an ISE module for sodium, potassium, chloride, and lithium. Service Manual Cobas Integra 400 Plus

Water Requirements: The system requires up to 2 liters of Type 1 NCCLS certified water per hour during operation. Preventive Maintenance & Service Procedures

Regular maintenance is critical to prevent hardware failures and ensure result accuracy. The service manual details specific intervals and procedures:

Daily Startup & Service Actions: The system is designed to perform automatic "Begin of Day" (BOD) service actions. Technicians must check the BOD report to confirm the status of automated flushes and electrode activations.

Cleaning Protocols: External cleaning should be performed only with a 70% propanol solution; organic solvents or bleach are strictly prohibited as they can damage plastic tubing and corrode metal parts.

Fluid System Maintenance: Comprehensive guides include cleaning the internal water reservoir with 0.6% sodium hypochlorite and replacing liquid filters (Filter Ligacon) to prevent contamination. COBAS INTEGRA® 400 plus - LABSERVIS LTD
