DEVICE AND METHOD FOR AUTOMATICALLY OPENING AND CLOSING A MATERIAL CONTAINER DURING A LYOPHILIZATION PROCESS

摘要

A device for storing a material to be lyophilized includes a support panel, a sidewall, an opening, a cover, and at least one lifter device. The sidewall and the support panel define a storage space for accommodating a material. The opening is defined by a rim of the sidewall. The cover is removably disposed adjacent to the rim of the sidewall for closing the opening. The lifter device is disposed between the support panel and the cover and includes a reservoir and at least one movable wall. The reservoir defines a sealed cavity containing a fluid. The movable wall is in operable communication with the fluid in the sealed cavity and engaging the cover to displace the cover away from the rim when the lifter device is subject to an ambient pressure that is less than the pressure of the fluid in the sealed cavity.
