Abstract: The invention is directed to a method for producing a roll (1) or sheet of membrane units (2) for a membrane product (3) such as a lateral flow test from a roll (6) or sheet of membrane material (7), by means of a primary production arrangement (9), wherein the roll (6) or sheet of membrane material (7) is processed into a roll (1) or sheet of membrane units (2) in a primary processing routine, wherein in the primary processing routine, for generating the membrane units (2), a fluidic structure (11), in particular a hydrophobic structure, for defining fluid flow through the membrane material (7) is introduced into the membrane material (7) by means of a processing tool (12), wherein an evaluation routine is performed by means of an evaluation arrangement (15) comprising a sensor arrangement (16) and an evaluation control (17).

Abstract: The invention relates to a product for providing membrane elements, comprising: a carrier film; and a membrane film, at least comprising: a support layer; and a membrane layer; the membrane film is releasably coupled to the carrier film; and the membrane film has a plurality of substantially discrete membrane elements. The invention also relates to a corresponding manufacturing process.

Abstract: The present invention relates to a patterned membrane structure comprising a microporous membrane layer, wherein the microporous membrane layer includes a plurality of flow lanes, the flow lanes are separated by hydrophobic separation channels, and the flow lanes and hydrophobic separation channels form a repetitive pattern; and a method for manufacture of the patterned membrane structure. The patterned membrane structure according to the present invention represents an industrial scale precursor of membranes such as a multiparameter lateral flow membrane comprising separated flow lanes.
