Sample processing device with resealable process chamber

摘要

Devices including resealable film used to define the volume of one or more process chambers in a sample processing device are disclosed. The resealable films provide for controlled puncture, followed by resealing of the puncture site such that the process chamber remains substantially isolated from the surrounding environment. The present invention also provides methods of manufacturing sample processing devices using resealable films, as well as methods of transferring sample materials into or out of a process chamber through a resealable film.
