A₂O Advanced Automated Osmometer

The A₂O is the premier multi-sample osmometer offered by Advanced Instruments. A₂O is smartly designed for laboratories requiring full automation of osmolality testing and true walkaway operation. A₂O combines a functional design, exceptional analytical performance, and an easy to use software control package that is elegantly simple to operate. It is ideally suited for today’s busy laboratories, which are being asked to achieve more results faster- yet with fewer resources. Osmolality testing without compromise… That’s A₂O.


Automated Multi Sample Capability

An intelligently designed 20 position sample tube carousel accommodates the most common laboratory sample tube sizes and shapes. Low volume inserts and nesting cups can also be used.

Touch-Screen User Interface

With a menu-driven operating system, intuitive software control, and multi-language capability, the A2O provides a simple operating experience at your fingertip.

Direct Primary Tube Sampling

Automatically transfers a 100 µl sample for analysis. This eliminates the manual pipetting step and improves accuracy while minimizing sampling errors.

Intelligent Liquid Handling Technology

The pipette system features liquid level sensing and crash detection circuity. This eliminates the guesswork involved with sample preparation.

Automated Self-Cleaning

The closed-loop fluid management system in the A2O cleans after each sample to eliminate sample carryover and cross contamination. These features provide flexible sample processing while minimizing sample carryover and cross-contamination.

Positive Sample Identification

An integrated bar code scanner eliminates transcription errors. Sample IDs can also be entered manually. The onboard printer provides additional sample identification and results reporting benefits.

Flexible Sampling Capabilities

Program the A2O to process samples in duplicate, triplicate, or any sampling protocol your laboratory requires.

Enhanced LIS and Data Management Capability

The A2O features bi-directional data communications as well as an on-board results database with search capability. Connectivity is a snap with Ethernet and multiple USB ports.

Built in Quality Control

The A2O comes complete with full list of QC features including: A supervisor mode with password protection, ability to set range limits for control solutions, statistical monitoring of daily QC, and a system events log for diagnostic purposes.
