Service Manual Cobas Integra 400 Plus: A Complete Guide for Biomedical Engineers Service Manual Cobas Integra 400 Plus
The Cobas Integra 400 Plus is a highly reliable, benchtop chemistry analyzer used in clinical laboratories worldwide. Manufactured by Roche Diagnostics, this system integrates four measurement technologies—absorption photometry, fluorescence polarization immunoassay (FPIA), immuno-turbidimetry, and ion-selective electrode (ISE) potentiometry.
Back up patient results, calibration curves, and QC data weekly onto an external storage drive.
Utilizes a high-intensity halogen lamp and a wheel with multiple filters to measure absorbance across specific wavelengths (340 to 800 nm).
The official Service Manual (often categorized under operator training or service technical manuals) is designed for qualified personnel. It provides essential information for: Execute an ISE calibration and check electrode slopes
Multi-stage rinsing stations clean the interior and exterior of the probe between cycles to eliminate sample carryover. Temperature and Incubation Control
: Ensuring adequate ventilation, stable power (100-240V AC), and a supply of Type 1 deionized water (up to 2L/hr).
: Intensive deep-cleaning and component replacement required to ensure accuracy for critical tests like glucose and kidney function.
The service manual provides detailed troubleshooting guides for common issues and error messages that may occur during operation. This includes: 1. System Overview and Core Modules
