ABSTRACT:
A reference electrode having a first tubular member, an elongate electrode element disposed within the tubular member, and a second tubular member disposed within the first tubular member to protrude out one end thereof is sterilized by aspirating through the first tubular member into the second tubular member a solution of HEMA and a salt dissolved in a solvent, evaporating the solvent, exposing the interior and exterior surfaces of the electrode to ethylene oxide gas, aerating the electrode, and immersing the electrode in a solution of said salt until the osmolality of the solution within the electrode and of the solution without the electrode is substantially the same.
