SEQUENTIAL DELIVERY OF FLUID VOLUMES AND ASSOCIATED DEVICES, SYSTEMS AND METHODS

摘要

The present technology is directed to capillarity-based devices for performing chemical processes and associated system and methods. In one embodiment, for example, a device can include a porous receiving element having an input region and a receiving region, a first fluid source and a second fluid source positioned within the input region of the receiving element; wherein the first fluid source is positioned between the second fluid source and the receiving region, and wherein, when both the first and second fluid sources are in fluid connection with the input region, the device is configured to sequentially deliver the first fluid and the second fluid to the receiving region without leakage.
