GEL101 Electrode Gel (Isotonic)

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:

  1. Abrade the skin at the point of electrode contact; you can use a nail file or an abrasion pad (such as EL PAD).
  2. Apply GEL101 to the skin at the point of electrode contact and rub it in.
  3. Fill the electrode cavity with GEL101.
  4. Attach the electrode to the subject.
  5. Wait several minutes (minimum) before starting to record data.
