Abstract
The present invention relates to a solvator plug for replenishing aqueous or non-aqueous solvents in devices such as electrochemical sensor cells. The plug includes a housing adapted to communicatingly mount to a cell or the like which houses a selected solvent for absorption by the cell. The solvent is maintained within the housing by means of an absorbant material or membrane and is delivered by virtue of osmotic pressure differences.
