A₂O Advanced Automated Osmometer

The next generation of osmometry

The new A₂O ® from Advanced Instruments is a fully automated, multi-sample osmometer that incorporates over 50 years of applied technology experience in the field of freezing point osmometry.

The A₂O combines a functional design, exceptional analytical performance, and an intuitive software control package that is both powerful and elegantly simple to operate.

Every aspect of the A₂O has been intelligently engineered to fully automate osmolality testing with ease and simplicity. It is ideally suited for today’s busy laboratories, which are being asked to achieve more results, faster — yet with fewer resources.
