Abstract: A method and system for processing a 3D tissue sample is provided, comprising the steps of receiving a tube with an inner space and two open ends, wherein the tube is configured to retain the 3D tissue sample in the inner space, arranging the tube so that one of the two open ends of the tube is located at a fluid channel, and forcing or actively pressing a tissue processing agent through the fluid channel and into the tube so that the tissue processing agent passes through the tissue.

Abstract: The invention relates to a fluidic system comprising at least one bead chamber (311) containing a lyophilized reagent (LB) and a reaction chamber in a cartridge. In one embodiment, a series of bead chambers with different lyophilized reagents may be provided such that sample fluid can sequentially pass through them. In another embodiment, bead chambers may be located on a movable carrier, for example a rotating carousel, from which they may selectively be connected to a reaction chamber in a cartridge. In still another embodiment, the bead chamber (311) may comprise at least one flexible wall (FW) allowing for a minimization of dead volume associated with the extraction of lyophilized reagent (LB).

Abstract: A microfluidic device (100) comprising at least one passive valve (PV, 120, 130), the passive valve being constituted by a sequence of a first carrier layer (CL 1) with an aperture providing a passage (P 1) for fluid flow, a first binding layer (BLI) with a first opening, a flexible layer (FL) with a through-hole (TH), a second binding layer (BL2) with a second opening, and a second carrier layer (CL2). Moreover, the flexible layer (FL) can move within a valve chamber (VC) constituted by the openings. Depending on the pressure difference across the passive valve (PV), the flexible layer (FL) can bend towards the first carrier layer (CLI) and close the aperture, while it opens the passage (P1) when bending in the opposite direction. Two of such properly oriented passive valves together with an intermediate active valve (AV) can constitute a one-stroke pump. A method for manufacturing such a fluidic device is also disclosed.
