CLEANING THE SS3LA TRANSDUCER
Do not leave GEL in the cavity after use. The electrode cavity must be left clean and dry. If GEL is left in the cavity,
it will act as insulation preventing electrical contact with the skin, and the Ag-AgCl electrode disk could degrade
quickly with time because the electrode surface is somewhat porous to promote good conductivity to the GEL.
To clean the reusable SS3LA, use a cotton swab or toothbrush with tap water.
Use any lab cleaner with pumice (such as Ajax) with a cotton swab or toothbrush to remove any dark residue from
the electrode surface.
Use Hydrogen Peroxide solution (2-3%) to brighten electrode surface (optional) or to sterilize the electrode. Do not
place the electrode in solution, but simply clean the electrode surface using a cotton swab. Dry the electrode off
completely before storage.
