The research of osmotic pressure instrument with high accuracy based on cryoscopy theory

Osmotic pressure gauge is widely used in the field of medicine and health. At present, the most commonly used osmotic pressure gauge have disadvantages of complex structure, high cost, low test efficiency and precision. For this reason, we propose a novel osmotic pressure test instrument in the paper, which is designed by cryoscopy theory. Meanwhile, the principle, the implementation scheme and functional characteristics of the system are introduced in the paper. The instrument has the advantages of small volume, high precision, fast detection speed etc.. In addition, the apparatus is designed with a data transmission interface, which is convenient for data analysis and comprehensive utilization.
