Osmolality can be measured on an analytical instrument called an osmometer. Thermal hysteresis is easily measured in the lab with a nanolitre osmometer. Freezing point depression osmometer is applied in various areas in the medical field. Freezing point depression osmometer will be applied in determining a solution's osmotic strength. The osmometer uses the solution's freezing point depression to establish its strength. The freezing point depression osmometer uses the solution's freezing point to establish its concentration.
