Patent ID: 8323462

Claim:
A device ( 8 , 78 ) for adjustment of the pH of a target liquid comprising: a housing ( 50 ) defining an enclosed interior ( 56 ) and having a base wall ( 54 ) at a tip thereof; a container ( 14 ) disposed within the enclosed interior and holding an electrolyte therein ( 16 ), the container having an open end that is coplanar with the base wall, the container including: a counter electrode ( 12 ) disposed within the container and being in electrical contact with the electrolyte; and a junction ( 18 ) located within the container and holding the electrolyte within the container, the junction spacing the electrolyte from a target liquid ( 20 ) when the working electrode is in contact with the target liquid; a working electrode ( 10 ) disposed within the enclosed interior; and a source of current ( 22 ) disposed within the enclosed interior, the source of current for supplying current to the working electrode for electrolysis of water at the working electrode, whereby the pH of the target liquid is adjusted.
