A disposable reactor (10) is provided for use with a co-operating instrument (20) to form an analytical device. The reactor includes a body of capillary material (14) housed in an enclosure (11, 15) having an opening for application of liquid to the body. At least one reagent (16) is immobilised in the enclosure. Also an electrode assembly (12, 12) passes through the enclosure, with one portion of the assembly extending within the enclosure to engage the capillary body and another portion of the assembly extending outside the enclosure, remotely from the enclosure opening, for connection with the associated instrument. |
