Applications
The Advanced Instruments Model 3250 Freezing Point Osmometer is widely used in hospital laboratories, clinical diagnostics, pharmaceutical quality control, biotechnology research, cell culture laboratories, food and beverage testing, environmental analysis, and industrial laboratories for precise osmolality determination.
Working Principle
The Model 3250 operates on the freezing-point depression principle. Dissolved particles lower the freezing point of a solution in direct proportion to their concentration. The instrument accurately measures this freezing-point depression and automatically converts it into osmolality (mOsm/kg H₂O), providing fast, precise, and repeatable results.
