A centrifugation device comprising a combined sample chamber and slide holder adapted to be mounted, with a microscope slide, in a centrifuge in a predetermined position, after placing a fluid biological sample containing cells in the sample chamber. According to the method, using a monitoring and evaluation system, signals from a number of sensors positioned in predetermined locations of a structure considered for energy efficiency retrofitting are received. The high bandwidth channel capacity of digital satellite systems is used for the download of large volumes of data. If the pathway is not established, the communications controller establishes this communication pathway and transmits the message. A liquid containing a target substance is fed from the openings.
