摘要： The present disclosure is to provide a method of mounting a membrane filter and a microfluidic device including the membrane filter, which are capable of increasing a flow pressure of a fluid. A salt matrix is attached to a region of a surface of the membrane filter that adjoins the filter support structure and is exposed toward the movement passage. A membrane filter and a microfluidic device including the membrane filter, which are capable of increasing a flow pressure of a fluid.

摘要： A method of manufacturing a microporous polymer structure (1) with at least one porous region (2) and a substantially non-porous support structure (3) configured to support said at least one porous region (2), the method comprising the steps of: i) providing a substrate (4); ii) providing a first composition (5) comprising a first polymer (5a), at least one solvent (5b) for said first polymer, and one or both of nanoparticles and microparticles (5c) dispersed within said first composition (5); iii) providing a second composition (6) comprising a second polymer (6a); iv) applying the first composition (5) to a surface (4a) of said substrate (4) to form a first coating layer (7); v) effecting a phase separation in the first coating layer (7) to obtain a phase separated coating layer (7'); vi) applying the second composition (6) to the same surface (4a) of said substrate (4) and/or onto the phase separated first coating layer (7'); vii) physically hardening or curing the second composition (6) applied in step vi) to obtain the non-porous support structure (3); viii) dissolving said nanoparticles and/or microparticles (5c) with a washing solvent to obtain the porous region (2); wherein said non-porous support structure and said porous regions are arranged on the substrate such that they form common interfaces, and wherein the phase separation in the first coating layer (7) in step v) is effected from one side of the first coating layer (7).

摘要： A piece of substrate material is formed under heat and pressure against a cavity into a shaped substrate sheet having one or more depressions. Two substrate sheets are bonded together to form a substrate wherein the one or more depressions form one or more interior channels. The substrate, if not formed with pre-coated substrate material, is coated with a dope and quenched to form a filtering membrane. A plurality of membranes may be placed side by side to form a bundle with permeating ends of the membrane, which are open to the one or more interior channels, separated by gaps or spacers. The bundle is connected to a header to produce a module. The module can be assembled into a cassette.
