Spectra 360 Electrode Gel, Parker Laboratories, 8.5 oz Tube (Pack of 5)

The only salt-free and chloride-free electrically conductive gel, recommended for all electromedical procedures, except defibrillation. Salt-free characteristics make it particularly suitable for long-term applications. Spectra 360 differs significantly from all other electrically conductive media...it works by wetting the skin, thereby reducing skin resistance.
