ECI Electro-Gel

Electro-Gel by Electro-Cap International, Inc. (ECI) is a perfect gel for EEG, evoked potentials (EP), brain computer interface (BCI), and brain-mapping measurements. ECI Electro-Gel ensures low electrode impedance for use with surface electrodes during EEG, EP, and other EXG measurements.

Comes in three different-sized bottles/tubs:

• 16 oz jar of ECI Electro-Gel can be used for roughly 75–90 EEG measurements using 20 electrodes
• 32 oz jar of ECI Electro-Gel can be used for roughly 150–180 EEG measurements using 20 electrodes
• 128 oz jar of ECI Electro-Gel can be used for roughly 600–720 EEG measurements using 20 electrodes

Specifications

• pH Value: 4.5
• Viscosity: 350 cps
• Water Solubility: Partial
• Ingredients: Water, Sodium Chloride, Aragum T-1998 (Gum Acacia, Guar Gum, Xanthan Gum), Potassium Bitartrate (Cream of Tartar), Glycerin, Methylparaben and Propylparaben

Application Notes

• Use as little Electro-Gel as possible, but enough to ensure good contact quality.
• Do not use on or near open wounds, bruised or weakened skin due to injury or medical condition of the patient.
• Avoid eye contact.
• If there is no hair at the electrode site, place a sponge disc (see below) around the electrode.
• It is not recommended that Electro-Gel be left in place for longer than eight hours for any single recording session.
• Do not use Electro-Gel with current-inducing electrodes.
• When finished recording, Electro-Gel may be removed from the scalp with mild soap and warm water, and from the cap and electrodes with Ivory (see below) liquid detergent and warm water.
• Electro-Gel is not to be reused.
