A supporting structure for concurrently supporting a plurality of containers having a predetermined length, the containers being used for the storage of substances for medical, pharmaceutical or cosmetic applications or contain such substances and each container having an upper end and a lower end, the supporting structure comprising
- a carrier having a plurality of supporting means and being configured to support and retain the containers on the carrier when in a first orientation and when in a second orientation opposite to the first orientation, wherein the supporting means comprises a protrusion that extends from a respective aperture of the carrier, wherein the protrusion is resilient and configured to pivot or flap away during insertion of the container into the aperture and supports the container in both the first orientation and the second orientation,
- wherein the supporting structure is formed in two parts comprising the carrier and a frame on which the carrier can be supported in a first carrier orientation or in a second carrier orientation opposite to the first carrier orientation,
- wherein when the containers are supported on the carrier in the first orientation and the carrier is supported on the frame in the first carrier orientation, the upper ends of the containers are arranged at a first distance to an upper rim of the frame,
- wherein when the containers are supported on the carrier in the second orientation and the carrier is supported on the frame in the second carrier orientation, the lower ends of the containers are arranged at a second distance to the upper rim of the frame,
- wherein the first distance is equal or substantially equal to the second distance, and
- wherein the upper ends and/or lower ends of the containers are accessible for a further processing of the containers, while they are supported on the carrier in the first orientation and in the second orientation.
