Processing Center

Sampling probe with integrated mixer and level sensing
The unique sampling probe streamlines sample and reagent level sensing, aspiration and mixing. That reduces complexity, enhances uptime and provides collision protection.

Combined sample and reagent rotor with cooling dome
The rotor ensures optimum temperature and humidity are maintained providing reagent on-board stability and integrity.
• 30 on-board reagent positions (inner ring with 15 cooled reagent positions).
• 25 sample, control and calibrator positions.

Disposable cuvettes
Reduced maintenance and water consumption while improving test turnaround time.

Bar code reader: test requisition, sample and reagent identification
Optional reagent and sample patient bar code further simplifies operations and eliminates potential errors.
