Title: The Innovative Contributions of Roy H Hammerstedt
Introduction
Roy H Hammerstedt is a notable inventor based in Boalsburg, Pennsylvania, with a remarkable portfolio of 14 patents. His work primarily focuses on advancements in the field of biological materials, showcasing his commitment to innovation and improvement in scientific processes.
Latest Patents
Among his latest patents is the "Integrated container for lyophilization, rehydration and processing of biological materials." This apparatus is designed to lyophilize, store, transport, rehydrate, and process aqueous biological materials while maintaining sterility. The container allows for shrinkage after lyophilization and optimally permits filtration or dialysis of the contents in situ, eliminating the need for additional containers. The construction of this microporous container features a membrane that is water vapor permeable yet water impermeable, ensuring the integrity of its contents.
Another significant patent is the "Interrogation of changes in the contents of a sealed container." This device and method enable the evaluation of the contents of a sealed primary container through an integral sensor. This sensor is separated from the contents yet provides valuable information on the quality of the contents without breaking the sealed system. The biosensor is retained within a plastic construct by a gated-pore membrane, which opens in response to environmental changes, allowing the contents to contact the biosensor. The status of the contents can be determined visually or via a fiberoptic probe through the optical window of the plastic construct.
