  • Patent number: 10794632
    Abstract: A cover plate for use in lyophilization processes is provided. The cover plate includes a base portion and a plurality of protuberances which project from the base portion. The protuberances are adapted to fit in one or more delivery containers, such as syringe barrels. The cover plate permits the escape of vapor from the one or more delivery containers during a lyophilization process. In addition, the cover plate prevents the escape of lyophilizate from the one or more delivery containers during a lyophilization process. Vent features provided to provide enhanced and preferred venting operations during lyophilization processes.
