We produce a high-precision osmometer to measure the osmolality of aqueous samples with a measuring range of 0 to 3000 m Osmole/Kg H2O, and a resolution of 1 m Osmole/Kg. The equipment features an on-screen display of molar concentration, freezing point, and osmolarity. The unit requires only a small volume of sample with a very low testing time it provides fast and accurate osmolality test results. It is efficient, and easy to use.
