Description
Key Features
- Run any assay from any vendor – fully automated open system allows incorporation of tests currently sent out.
- Customizable assay parameters – automate sample distribution, incubation, reagent addition, washing, and detection steps. Customize OD read settings, result calculations, QC checks, and report formats.
- Reliable workload scheduling – 98.5% uptime over the past 2 years when mean time between failure target is set at 250 days. Schedule preventive maintenance during slow periods.
- Electronic Signature Pipetting (ESP) – detects gross pipetting errors caused by clots, foam, bubbles, or particulate matter. Reports insufficient sample transfer during a run.
- Prevent unscheduled downtime – robust automation reduces manual intervention.
- Space-saving design – footprint <4 square feet, processes up to 2 × 96-well microplates or 100 specimens, ideal for expanding workloads.
