Abstract: A tray is provided for receiving a plurality of pre-filled syringes each having a tubular body defining an outer surface and a chamber having an open first end sealed with a plug and an open opposite second end configured to establish fluid communication with a hypodermic needle, wherein a flange extends from the tubular body at the first end. The tray includes a plate defining a plurality of through-going ridges and a plurality of through-going grooves parallel to the ridges, wherein the ridges are interconnected with the grooves. A multitude of open apertures is defined at the ridges, wherein the apertures are configured for (a) receiving the flange of a syringe received between two adjacent ridges, and (b) permitting the passage of a gas through the plate to contact the outer surface of the syringe.

Abstract: A method of detecting unwanted objects or faults in containers containing a fluid or liquid includes: (a) moving the containers along a path of travel; (b) providing; a light source emitting light of a specific spectral distribution, wherein the containers and their contents are at least partly transparent or translucent at the specific spectral distribution; (c) providing a camera for detecting light at the specific spectral distribution, wherein (1) the path of travel intersects a field of view defined by the camera, and (2) the camera registers a sequence of digital images as the containers pass between the light source and the camera; (d) selecting a part of each of the digital images that corresponds to the outline of a specific container; and (e) processing a sequence of the parts of the digital images so as to detect the unwanted objects or faults in the specific container.
