An osmometer is a specialized instrument designed to measure the osmotic pressure of solutions, a key parameter in fields such as biochemistry, medicine, food science, and environmental monitoring. By determining osmotic pressure, it helps assess the concentration of dissolved solutes in a solution, which is critical for applications like cell culture maintenance, clinical diagnosis (e.g., measuring urine or blood osmolarity), and quality control of beverages or pharmaceuticals. This guide provides a step-by-step overview of how to use an osmometer correctly, safely, and efficiently.​
