Understanding Permeability: Definition and Examples

Permeative refers to a substance or a process that allows something to pass through it, especially a liquid or a gas. In other words, it is a substance that is permeable, meaning it has pores or openings that allow the passage of molecules or particles.

For example, a permeable membrane in a laboratory setting might be used to separate different types of cells or molecules based on their size or properties. Similarly, a permeable material in construction might be used to allow water or air to pass through it, such as a permeable concrete or a permeable fabric.

In general, the term "permeative" is used to describe any substance or process that allows the passage of something else, whether it's a liquid, a gas, or even a type of energy.
