Abstract: A filter press device includes a supporting frame and elongated side rails disposed parallel and horizontally on the supporting frame. A following head assembly is disposed on an end portion of the supporting frame, and a following head assembly is movably disposed on another end portion of the supporting frame. The elongated side rails support a combination of filter plates of varying sizes through one or more adapters. An adapter plate interposes between adjacent filter plates of different sizes, providing fluidic communication between the different sized filter plates.

Abstract: The invention relates to an isolated waterproof polymeric nanomembrane comprising pores of different geometric shapes and of a controlled size between 10 and 1000 nm, which is larger than the thickness of the membrane, and a method of producing the same comprising the process steps a. Providing a sacrifice layer on a surface of a solid support; b. Providing a polymerized layer of less than 1000 nm thickness on the surface of the sacrifice layer, by depositing a mixture of a polymer or a polymer precursor with a geometrically undefined pore template which is larger than the thickness of the polymerized layer, optionally followed by polymerization and/or crosslinking; c. Removing the pore template to obtain the polymerized layer with a controlled pore size; and d. Removing the sacrifice layer, thereby separating the solid support from the polymerized layer.
