Osmometry

Concentration determination is one of the most widely useful laboratory measurements, with applications ranging from quality control in the manufacture of pharmaceuticals, food products, eye care solutions, to monitoring the fluid balance and hydration processes of animals from fish to humans.
We offer the widest range of osmometers, with sample sizes ranging from 10ul to 2ml, and with various levels of automation. For a guide to choosing the best osmometer for your application, click here.
Today, due to their high reliability, and industry-leading cost per test, thousands of PSI osmometers are in daily use around the world.
