The cobas t 511 and cobas t 711 Coagulation Analyzer systems are leading solutions from Roche, marking a new era in laboratory coagulation testing. Designed for medium to large-volume laboratories, these two instruments offer an optimal combination of safety, efficiency, and productivity, aiming to meet the increasing demand for fast and accurate results while optimizing costs. The cobas t 511 and cobas t 711 systems are fully automated, continuous random-access coagulation analyzers, performing clotting time detection using optical measurement methods such as chronometric, chromogenic, and immuno-turbidimetric assays. Test results support the diagnosis of coagulation abnormalities and monitoring of anticoagulant therapy.

Key Features and Benefits:

• Powerful Processing Capability:
  • High throughput: cobas t 511 achieves 195 tests/hour (PT/APTT), while cobas t 711 reaches 390 tests/hour (PT/APTT).
  • Superior on-board reagent storage capacity: With 57 reagent cassette positions, the system can store up to 34,200 tests on board, with reagent on-board stability of up to 2 weeks.
  • Large sample capacity: cobas t 511 holds 75 samples, and cobas t 711 holds 225 samples.
  • Flexible sample loading/unloading: Both instruments allow for automatic and continuous sample loading/unloading via the front loading port. The cobas t 711 also has a side tray and connectivity to cobas® 8100 automation system and cobas® CCM, providing maximum flexibility.
  • True STAT capability: Has a dedicated position for urgent samples, ensuring priority processing without interrupting ongoing runs.
• Seamless Workflow:
  • Continuous loading/unloading: Samples, reagents, and cuvettes can be loaded and unloaded at any time, along with liquid and solid waste disposal during operation, optimizing hands-off time.
  • Diverse tube handling: Supports open and closed tubes, compatible with various vendors, and automatically rotates tubes for accurate identification.
  • e-Services: Provides access to an electronic library, LIS connectivity, and remote technical support functions.
  • High-quality results: Ensures result reliability with features like HIL indices, clot detection, automatic cuvette checks, and full result traceability.
• Specialized Automated Reagent Management:
  • Fully automated reagent reconstitution: Eliminates user-related risks during reagent preparation, ensuring quality and maximizing reagent performance.
  • cobas t pack reagent cassette concept: Contains 3 separate reagent tubes, stored in a refrigerated on-board compartment (5 – 12 °C), with a design that eliminates contamination or evaporation risks, allowing for easy loading/unloading.
  • Full automation from loading to preparation: cobas t packs are automatically transported from the refrigerated compartment to the upper chamber, data is automatically entered via barcode, and automatic pipetting, mixing, and room temperature adjustment occur.
• Safe and Reliable Design:
  • Automatic cap piercing: Compatible with various cap types, minimizing exposure risk and injury to users.
  • Automatic barcode scanning: Integrated for samples and reagents, ensuring safety and accurate traceability.
  • Result traceability: Allows verification of lot information for calibrators, controls, and reagent lots used to obtain results.
  • Minimal maintenance: Daily maintenance time is only 5 minutes, and only requires periodic maintenance once per year, optimizing uptime and cost-efficiency for the laboratory.
