GEL101 electrode paste is specially formulated with 0.5% saline in a neutral base. Unlike agar or saline pastes, this paste has a virtually unlimited shelf life. It is supplied in a 4 oz. bottle with a convenient flip-top reclosable cap.
GEL101 Electrode Paste meets all of the recommended specifications for skin conductance recording.
- The "Unibase" material called out by Lykkenand Venables in Psychophysiology, 1971, pp. 665 - 666 no longer exists.
This non-irritating, isotonic paste is primarily used as a conductant for electrodermal response electrodes, such as BIOPAC's TSD203, SS3A, and SS3LA, but it can be used with any premium Ag/AgCl electrodes.
Usage Recommendations
When using GEL101 it is important that the gel has a chance to be absorbed and make good contact before recording begins. Accordingly:
- Abrade the skin at the point of electrode contact; you can use a nail file or an abrasion pad (such as EL PAD).
- Apply GEL101 to the skin at the point of electrode contact and rub it in.
- Fill the electrode cavity with GEL101.
- Attach the electrode to the subject.
- Wait several minutes (minimum) before starting to record data.
