Abstract: The cassette arrangement is used to accommodate boxes or the like, in particular petri dishes. This arrangement is characterized by a shäll.ow box-shaped cassette housing designed to be stackable and having a slotted opening an one end face for inserting or removing a box or a dish and having finger-operated means arranged an the opposite end face for pushing the dish out at least partially through the opening in the cassette housing. Through these measures, safe handling and transport of petri dishes or the like is now guaranteed. The cassette arrangement also permits secure stacking and problem-free removal of individual boxes or petri dishes from the stack.
