Abstract
A disposable element is provided for use in analytical equipment for electrochemical determination of biological cells. The disposable element comprises a working electrode, a reference electrode, and a filter for retention of solids in the vicinity of the electrodes. The analytical equipment with disposable elements can be used for respiratory assays, enzyme assays or immunoassays, among other uses. In a variation, the disposable element comprises a reference electrode, working electrode and fusible link.
Claims13
A disposable element for use in analytical equipment for a bioelectrochemical determination, the disposable element comprising a base plate having an aperture for flow of liquid through said element, a working electrode coated on a face of said base plate, a reference electrode coated on said face of said base plate, and a filter in contact with said electrodes for retention of solids in the vicinity of said electrodes for determination.
Analytical equipment for a bioelectrochemical determination using a working electrode coated on a face of a base plate having an aperture to allow flow of liquid past said electrode and a reference electrode coated on said face of said base plate, wherein said base plate, working electrode, said reference electrode, and a filter in contact with said electrodes for retention of solids in the vicinity of the electrodes, are provided as a disposable element, and wherein the analytical equipment has receiving means for releasably receiving the disposable element.
A disposable element for use in analytical equipment for a bioelectrochemical determination, the disposable element comprising a base plate having an aperture for flow of liquid through said element, a working electrode coated on a face of said base plate, a reference electrode coated on said face of said base plate, a fusible electrically conducting link which may be fused to ensure single use of the disposable element, and a filter in contact with said base plate for retention of solids in the vicinity of said electrodes for determination.
