Diffusion cell with filter screen |
摘要 |
A diffusion cell to facilitate the automated removal of test aliquots of liquid from a receptor chamber of the diffusion cell so as to determine percutaneous absorption through a membrane of a donor media from a donor chamber into the receptor chamber of the diffusion cell. There is utilized a sampling port through which the test aliquot is to be removed, the removal being achieved by means of a sample tube. Within the receptor chamber is located a stirring device in the form of a helical coil which is to be rotated to achieve stirring and homogeneous mixing of the liquid within the receptor chamber. Mounted within the coil is a filter screen to prevent particulate matter over a certain size from entering the sample tube and clogging such.
