The advanced solution in 5-Part-differential hematology. The instrument uses well established methods such as impedance and photometric measurements as well as an innovative optical measurement (laser-based scattering technology) in order to guarantee precise and accurate 24 parameter complete blood count profile including 5-part WBC differential results. The autoloader unit enables a walk-away automation of closed tube sampling, including cap-recognition and cap piercing, with a capacity of 100 vials at a throughput of 60 samples per hour.
