1. A method of producing a reagent tape, that comprises a base tape layer and a series of consecutive and separate reagent pads of a reagent, for use in a milk sampling device, the milk sampling device being arranged to supply a droplet of a milk sample onto one of the reagent pads on the tape in order to produce a response in the reagent to detect a presence or concentration of a substance in the milk sample, the method comprising:
providing the base tape layer of the reagent tape;
applying onto the base tape layer a continuous layer of the reagent; and
dividing the supplied continuous reagent layer into separate reagent pads by providing a hydrophobic barrier line,
wherein the step of providing a hydrophobic barrier line comprises removing two mutually parallel strips of reagent in a direction transverse to a longitudinal direction of the tape by laser ablating to form neighboring reagent pads.
