    laboratory devices measuring substance diffusion through barriers

    Franz diffusion cells are laboratory devices used to study the rate at which substances, such as drugs or cosmetic ingredients, pass through a barrier, typically skin or a synthetic membrane. They consist of two chambers separated by the barrier: one chamber holds the test substance, while the other contains a fluid that collects the diffused substance, allowing researchers to measure how quickly and effectively the substance penetrates the barrier.
