👉 A comparable fluid, often referred to as a "compatible solvent," is a substance that can be used in place of or alongside the original fluid without causing adverse reactions or significant changes to its properties. This is particularly important in medical and laboratory settings where maintaining the integrity of the fluid is crucial. For example, in clinical diagnostics, a compatible solvent might be used to dilute or adjust the pH of a blood sample without altering its chemical composition, ensuring accurate test results. Similarly, in industrial processes, a compatible solvent can replace the original fluid to prevent contamination or degradation, preserving the fluid's functionality and stability.
