Abstract
A device and related method are provided for lyophilizing a substance within the device and storing therein the lyophilized substance. The device is penetrable by a needle for filling the device with the substance to be lyophilized, and a resulting needle hole in the device is laser resealable by transmitting thereon laser radiation from a laser source. The device defines a chamber for receiving therein the substance to be lyophilized. A needle penetrable and laser resealable portion of the device is pierceable with a needle to form a needle aperture therethrough to fill the chamber with the substance to be lyophilized through the needle, and is laser resealable to hermetically seal the needle aperture by applying laser radiation thereto. A filter is connectable in fluid communication between an interior and exterior of the chamber for permitting fluid to flow therethrough in a direction from the interior to the exterior of the chamber, and for substantially preventing contaminants from flowing therethrough in a direction from the exterior to the interior of the chamber.
