Multi Sample Osmometer Improves Testing Efficiency

A novel 20-position micro sample osmometer improves laboratory efficiency, productivity, and workflow by reducing sample turn-around time.

The OsmoPRO Multi-Sample Osmometer for automated osmolality testing is designed to analyze a variety of complex aqueous mixtures, including blood, serum, plasma, urine, cell culture media, drug formulations, and biological cell therapies, using a small, 20 μL sample size. Samples can be analyzed one at a time, or batch processed depending on workflow demands. Timesaving features include an intuitive touch screen, automated processing, and the ability to run unattended. The device also uses the freezing point depression method to deliver results in just two minutes.


The OsmoPRO can be used in a variety of laboratory applications including clinical diagnostics, formulation development, bioprocess monitoring and process control, industrial, environmental, and finished product quality control. An integrated barcode scanner provides positive sample identification to reduce transcription errors, with data management and transfer handled via the on-board printer or by exporting the data using an ethernet connection and multiple USB ports. The OsmoPRO multi-sample osmometer, a product of Advanced Instruments (Norwood, MA, USA), will be presented at AACC 2016.

“OsmoPRO incorporates more than 60 years of applied technology and expertise from Advanced Instruments, the industry leader in the field of osmometry,” said Peter Costas, vice president of sales and marketing at Advanced Instruments. “OsmoPRO replaces the Advanced Model 2020 osmometer, which has been an extremely popular and reliable osmometer used in thousands of laboratories worldwide, and represents Advanced Instruments commitment to quality and innovation in the field of osmometry”.

Osmometers are used for measuring the osmotic strength of a solution, colloid, or compound, or determining the molecular weight of unknown compounds and polymers. Several techniques can be used, including vapor pressure depression to determine the concentration of osmotically active particles; determining the osmotic pressure of a solution separated from pure solvent by a semipermeable membrane; and freezing point depression to determine osmotically active compounds in a solution.

The American Association for Clinical Chemistry (AACC; Washington, DC, USA) is an international scientific/medical society of over 8,000 clinical laboratory professionals, physicians, research scientists and more. The AACC annual meeting, which will be held from July 31st to August 4th at the Pennsylvania Convention Center in Philadelphia (USA), features five days of educational sessions on scientific, clinical, technical and management challenges facing laboratory professionals, as well as the world’s largest Clinical Lab Expo.
