The Convergys ® ISE NG is a Fully automatic ISE based Electrolyte Analyzer to measure Na+, K+, Li+, Ca++, pH and Cl- concentrations in blood, plasma, CSF and urine. Convergys ® ISE NG is designed, developed and manufactured in Germany. It has a very compact design and the only interface is an extremely use-friendly LCD touch panel with logically assigned menu structures. The aspiration system is integrated inside the equipment affording an enhanced operator safety and also minimizing the risk of needle contamination. The aspirate probe is designed to accommodate the test samples from a sample cup, capillary or collection tube. The calibrators CAL1 and CAL2 are packed in a cartridge to avoid any undue contamination. With an on-screen Reagent Management System the operator is able to monitor the status of reagents as well as of waste bottle. Both CAL1 and CAL2 can be replaced independently to optimize the operating costs. A dedicated tubing design ensures minimized clogging and an integrated air-liquid-air-liquid rinsing mode helps avoid carry over.
