ANALYTISCHES TESTGERAET.

摘要

An analytical device (10) for the qualitative and/or quantitative determination of an analyte in a liquid test sample, comprises a base (12) supporting a porous member (16) which has an analyte-responsive substance therein, the substance being capable of undergoing a detectable response to the presence and/or concentration of analyte in the test sample. A cover (18) integral with the base (12) is provided with a reaction well (28) formed therein for storing a dried reaction component (34) and for receiving the liquid test sample to form (with the reaction component) a liquid reaction mixture therein. The reaction well has a passage (30) which is normally spaced from the porous member (16) and effectively closed to transfer therethrough of the reaction mixture, but which is movable towards the porous member effectively to open the passage to allow flow therethrough of the reaction mixture into the porous member (16). The analyte responsive substance in the porous member will undergo a detectable response to any analyte present in the liquid reaction mixture. The base can be provided with a suitable viewing port (54) to permit monitoring of the detectable response generated in the porous member.
