universal rack for reagent containers, controls, and calibrators for regular, stat, and pediatric samples; user decides which ones and how many rack positions to allocate for each; compact, economical instrument designed to bring automation to lower-throughput labs and for use as a backup to larger systems cost-effective with long-life IAD filters; self- prompting touchscreen with mouse-compatible interface for easy selections and entries; optional built-in flow cell for reduced sample volumes dilution, predilution, dispensing single or multiple reagents; carryover is eliminated without the need for disposable pipette tips; wash cup assures cleaning inside and out; probe is temperature- controlled to deliver 37°C reagents
