👉 Restricted fluid, also known as colloid-free fluid or colloidal-free fluid, refers to a type of liquid that lacks suspended particles or colloids. In this fluid, the molecules are too small to form visible particles that would settle out over time, unlike in normal colloidal solutions where particles are too large to remain suspended indefinitely. This results in a fluid that appears clear and stable but does not exhibit the typical properties of colloids, such as sedimentation or creaming. Examples include pure water and many industrial fluids used in manufacturing processes where maintaining a stable, clear liquid is crucial.
