A₂O Osmometer

The Advanced Automated A₂O® Osmometer with its fully automated multiple sample determination and an extended range of 0-4000 mOsm/kg H₂O is the most comprehensive model from Advanced Instruments. A₂O® is designed for laboratories requiring complete automation of osmolality testing and high sample throughput. The removable sample tray provides space for 20 different sample vessels from which 100 µl are automatically taken for osmolality determination. This eliminates the time-consuming pipetting step. The integrated barcode scanner simplifies sample identification. The method of freezing point depression and the automated pipetting offer the highest precision and reliability and thus optimize your quality control. 

A₂O® combines a functional design, exceptional analytical performance and an easy-to-use software control package. The A₂O® features bi-directional data communication as well as an on-board results database with search capability. Connectivity is possible with Ethernet and multiple USB ports. Data can also be exported directly from an integrated printer.
