Laser ablation machine for labeling vial frozen at cryogenic temperatures

摘要

The present invention relates to a machine for labeling " blank-labeled " cryogenic vials or ampoules containing non-heat resistant biological materials and applying a laser light sensitive material before freezing. Therefore, the machine is designed to maintain the integrity of biological materials throughout all phases of the labeling process. The machine is usually a master control system; Programmable user interface; frame; Cryogenic freezer assemblies to maintain the vials at the required low temperatures; An infeed assembly configured to receive and position blank-labeled cryogenic vials; A low temperature maintenance labeling / quality control tunnel in which vials are maintained at the required temperature, labeled by laser ablation, and checked for quality; And an outfeed assembly. The machine further comprises means for transporting the vials from the infeed assembly to the tunnel and from the tunnel to the outfeed assembly. The vials labeled in accordance with the present disclosure are eventually loaded manually or automatically into cryogenic shipping containers.
