▎ 摘  要

NOVELTY - The assembly (100) has a first microchannel substrate (102) that defines a first microchannel. A second microchannel substrate (104) defines a second microchannel. A membrane is arranged between the first and second microchannel substrates, where the membrane comprises a first polymeric layer (158) and a second polymeric layer (160). A graphene layer (162) is formed between the first and second polymeric layers. A portion of the first microchannel overlaps a portion of the second microchannel when first fluid is present in the first microchannel and second fluid is present in the second microchannel, where the first fluid and the second fluid contact opposite sides of the membrane. USE - Microfluidic assembly for filtering products from waste streams in laboratory environments and reclaiming products for purposes of recycling. ADVANTAGE - The assembly can be used to efficiently separate extremely small particles from a fluid, and can be adjusted to select which particles are separated from the fluid flowing through the system. The risk of leakage is mitigated. The assembly can utilize thinner membranes, thus saving space. The properties of the membranes can be selected or controlled depending on the desired products to be removed. The quartz chips are reusable and easily made. The membrane system is chemically stable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for filtering products from waste streams in laboratory environments and reclaiming products for purposes of recycling. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded side view of a microfluidic assembly for filtering products from waste streams in laboratory environments and reclaiming products for purposes of recycling. 100Microfluidic assembly 102First microchannel substrate 104Second microchannel substrate 158First polymeric layer 160Second polymeric layer 162Graphene layer
