A modification in the design of the valve seat of the static mercury drop electrode is presented. The creation of a 'four-point' seal within the modified valve seat prevents the capillary 'O' ring seal from becoming flattened and distorted. The design has eliminated air leakage into the system, and as a result, breaks in the mercury and premature drop detachment are virtually non-existent.
