?Wiener lab. CT 300i is a random access clinical chemistry system for routine and special chemistries, including specific proteins, electrolytes, therapeutic drugs, and drugs of abuse tests. The broad range of CE marked applications can be complemented with userdefinable tests. Throughput Workload dependent, being in typical routine use up to 300 tests/hour until 480 t/h with ISE. Time to first result is typically 3 to 12 minutes. Samples Continuous access to samples without interrupting test processing. Optional automation interface, KUSTI. On-board capacity: 84 routine samples and 6 STAT samples 6 segments with 14 positions per segment. Integrated barcode reader and cup/tube recognition. Sample cups and tubes: 0.5 ml and 2.0 ml cups, 5 ml and 7 ml tubes, 10 ml tubes with tailored segments. Sample types: Serum, plasma, urine, CSF. Sample volumes: Possible range 1-120 ?l ; typically 2-15 ?l and 50 ?l for Na+, K+ and Cl- ISE tests. Reagents Continuous access to reagents without interrupting test processing. Automated indentification by integrated barcode reader. Real time reagent status clearly displayed. Up to four reagent additions / test possible. On-board storage: 45 positions in the refrigerated reagent compartment. Reagent vials: 10, 20 and 60 ml Reagent volumes: 2-250 ?l; typically 120 - 200 ?l.
