Abstract: An apparatus is provided for optically inspecting containers of liquid solutions. The apparatus includes a fixture for gripping the container and a conveyor or indexable table for moving the fixtured container into alignment with a camera or other optical inspection device. The apparatus further includes a vibrator at the inspection station. The vibrator causes the container of the liquid solution to vibrate sufficiently for extraneous material in the solution to move into a position that permits accurate visual inspection.

Abstract: An inspection apparatus is provided for accurate identification of particulates in parenteral drugs. The inspecting apparatus includes a black inspection panel having an aperture extending therethrough. A light-tight enclosure surrounds the aperture in the panel on the side of the panel opposite the side on which the parenteral drug is inspected. Interior surfaces of the enclosure have black surfaces with finishes to achieve low light reflection. The combination of the aperture and the black enclosure provides enhanced blackness that is not likely to be affected by dust, dirt or surface damages. Hence, greater accuracy and reliability in black background particulate inspection is achieved.
