Diffusion cell for testing ointments and the like. The cell comprises at least two body members (2 and 3) which define a closed diffusion chamber which is divided with a membrane (7) into two chambers, i.e. an ointment chamber (8) for the ointment to be tested, and a receptor chamber (9) for a receptor medium and provided with an inlet and an outlet for the receptor medium. The ointment chamber is provided with a hole disk (11) to be brought into engagement with the upper surface of the membrane (7) and provided with at least one hole (13, 14) for receiving the ointment to be testted, as well as holding means (16) for cooperation with the hole disk and the inner wall of the ointment chamber so that when the cell is assembled and closed, the holding means lock the hole disk with optionally interleaved skin sample into contact with the membrane. |
