Following the reliable and successful operation of the multiple processes ,the unit processes which were designed to supersede them followed the basic pattern of the multiple system .thus ,unit processes based on enclosing a stack of plates in a vessel were developed ,reminiscent of a rack of bottle .such systems were made from disposable polystyrene or polycarbonate as well as soda glass .later development took a stack of plates and rotated them either with the plane of the plants in the vertical configuration or ,more recently ,with the plates in the horizontal configuration.This latter system has been scaled-up and is at present under intensive exploitation as a means of producing the β-or fibroblastic interferon problems during the cleaning and cell planting operations .the amount of surface which can be packed into a container in this way is limited ,which has two consequence
