Discrete Fluid Samples Microextractor

A discrete fluid samples microextractor is presented in this paper. The main advantage of this device is that the extraction is controlled, not only in time but also in fluid volume. A one shot valve is in charge of extracting a certain quantity of fluid in the fixed moment. It is designed to be integrated in array, so the final design is composed by several modules which are activated sequentially to extract fluid samples throughout the time. It is manufactured in polymer to reduce its cost Experimental results that prove feasibility of design are commented.
