Osmolality standards

Supplier: REAGECON

Osmolality standards provide ease of use when calibrating all types of osmometers. All Osmolality standards are manufactured using high purity raw materials. These products are prepared gravimetrically on a weight/weight basis. Both solute (salts) and solvent (water) are weighed on a balance calibrated by using OIML traceable weights.
