Caputron Focus Sponge Inserts


Pack of 10 high quality replacement sponges for sponge electrodes. Comes dry and expands when wet.

These Sponge inserts by Caputron were specifically designed for use with the Focus Go Flow tDCS device electrodes.

Pack comes with 10 sponge inserts.

Over time the sponges within the electrodes can grow brittle and crumble, crack, or split causing an uneven distribution of current. It’s a good idea to replace your sponges often to ensure that the electrodes function properly. It is advised that you replace your electrode sponge inserts every 3-4 uses.

These sponges come dry. As soon as one applies saline solution to them, they immediately absorb the solution and expand. They work best when inserted into the rubber electrode pad first as they expand quickly when wet. They provide excellent contact with and conductivity to the application area.
