• Colourimetric/Rate methods for general chemistry assays.
• Immuno-rate methods for specialised testing.

Its compact footprint, no plumbing requirement, and straightforward daily maintenance make it adaptable to various laboratory environments.

Core Features of the VITROS 250 analyser

1. MicroSlide™ Technology

• Ensures precise and reliable results.
• Reduces interference from haemolysis, lipemia, and bilirubin.
• Requires only 5.5–11 µL sample volume.

2. Automation & Workflow Efficiency

• SMART Metering™ provides accurate sample handling with bubble and clot detection.
• On-board dilution streamlines workflows.
• Simple operation with a touchscreen interface.

3. Sample Handling & Management

• Capacity for 40 samples with flexible tray formats.
• Supports multiple sample container types, including tubes and microtubes.
• Barcode scanning for positive patient identification.

4. Quality Control & Calibration

• Calibration stability up to 6 months.
• Daily QC checks are required only once.
• Extended calibration supports multiple reagent lots.

5. Environmentally Sustainable Design

• No drains, vents, or deionised water required.
• All waste is contained in disposable slides, promoting safer lab practices.
