摘要：A multifunctional filtration apparatus is provided for the automated transfer,separation and filtration which accommodates all types of filter papers or filter mediumsincluding aerophobic filter mediums such as nitrocellulose, nylon, biological membranesas well as aerophyllic filter mediums. The automated multifunctional filtration apparatusincludes a first manifold and one or more separation chambers disposed on one side of afilter medium and a second manifold disposed on the other side of the filter medium. Themultifunctional filtration apparatus provides for the high speed transfer, separation ofgaseous and liquid components of a fluid before filtration without cross contamination ofmultiple samples by utilizing the first manifold to transfer fluids containing filtrablesubstances from test tubes or sample plates to a separation chamber disposed abovethe filter medium where the gases and liquids are separated and the gases removedbefore the utilization of the second manifold to provide for the filtration of the filterablesubstances on the filter medium. Subsequent addition of wash fluids or reagents forfurther reaction of the filterable substances can also be accomplished utilizing the novelmultifunctional filtration apparatus. As a result the automated multifunctional filtrationapparatus can be used for all types of filter paper or filter mediums used such as paper,glass, fiber synthetic and traditional filter papers as well as biological membranes or

filter mediums having reactive or reactable surfaces for filtering and reacting capturedfilterable substances.
