ELECTRODE ACCESSORIES & GELS
Abrasive Pads
Before applying electrodes, abrade the skin lightly with an ELPAD (above left) to remove non-conductive skin
cells and sensitize skin for optimal adhesion. Each ELPAD package contains 10 abrasive pads.
Adhesive
Use adhesive
tape for attaching Active Electrodes and other devices. Use the preferred tape or BIOPAC’
s
adhesive tape: TAPE1 single-sided; TAPE2 double-sided. (Above center)
Adhesive Disks
ADD200 series double-sid
ed adhesive collars are used to hold reusable electrodes (EL254/8R
T) firmly on the
skin surface. (Above right)
ADD204 19 mm outside diameter, use with EL254 and EL254S
ADD208 22 mm outside diameter, use with EL258 and EL258S
MRI Use: MR Safe
ADD204/208 Adhesive Disks Components:
Disks: 3M hypoallergenic medical tape – Acrylic polymer
Electrode Gels
GEL1 & GEL100 Non-irritating
, hypo
-allergenic gel used as a conductant with the EL250 series reusable
electrodes. GEL1 = 50 g; GEL100 = 250 g
MRI Use: MR Conditional
Condition: Max MR field strength 3T
GEL100 Components:
Water, Sodium Chloride, Propylene Glycol, Mineral Oil, Glyceryl
MonostearatePolyoxyethelene Stearate, Stearyl Alcohol, Calcium Chloride, Potassium
Chloride, Methylparaben, Butylparaben, Propyl Paraben
GEL101 Non-irritating, isotonic gel is primarily used as a conductant for the TSD203 electrodermal
response electrodes. Each tube contains 114 g (~4 ounces).
GEL101 is 0.5% Saline in a neutral base and is the appropriate GEL to use for GSR, EDA,
EDR, SCR, and SCL. This electrode paste has an approximate molarity of 0.05M NaCl and is
0.5% Saline; the Saline concentration is adjusted to obtain a final paste molarity of 0.05M
NaCl. This particular molarity is in line with the recommendation made by Fowles (1981).
