A sequential processing apparatus, particularly for use in pathology especially histology, comprises support means for supporting at least one row of baths above another row and mechanism for stepping said rows of baths in opposite directions. A transfer device at one end of the rows of baths transfers baths, one at a time, from the upper row to the lower row and a transfer device at the other end of the rows transfers baths, one at a time, from the lower row to the upper row. A specimen or slide carrier is positioned so as to be above the path of movement of at least one of the rows of baths, mechanism being provided for lowering and raising said carrier so as to immerse a specimen or slide in or withdraw it from a bath. In one preferred embodiment of the invention there are two side-by-side groups of baths, each group comprising upper and lower rows of baths and the specimen or slide carrier is moved periodically across the apparatus from a position over a row of baths of one group to a position over a row of baths of the other group.
