Abstract
Abstract This invention relates to a new disposable cuvette for essentially simultaneous sampling a fluid and analysing the sample. The new cuvette comprises a body member having at least one cavity defined by surrounding walls, into which cavity a sample is permitted to enter by capillary force through an inlet communicating said cavity with the exterior of the body member. According to the invention the cuvette is characterized in that at least one part of the walls facing the cavity consists of a semipermeable membrane, optionally with an integrated electrode and/or sensor system and that at least one reagent or reagent system is incorporated in the cuvette.
