The ideal way to carry and apply saline solution to your sponge electrodes

This 2 ounce, squeezable bottle takes the hassle out of applying saline solution to sponge electrodes. The small tip opening is the perfect size to dispense the solution at a flow rate that won’t over soak the electrodes. Additionally, if you’re using Amrex sponge electrodes, this squeeze bottle will allow you to apply saline solution directly to the sponges, without needing to remove them from their rubber casing. Furthermore, we placed instructions on the back of the bottle which explains how to effectively mix your saline solution.

Please Note: This bottle ships empty, but contains instructions for mixing your own saline solution.

Product Description

What is Saline Solution, and why do I need it?

Saline solution is a simple mixture of salt and water which is soaked into sponge electrodes for tDCS. Plain water in and of itself  is a very poor conductor of electric current. However, by adding salt to the water, electric current can “jump” across the salt molecules, helping to form a complete connection. By using salt water (saline) with your sponges, you greatly increase the conductivity of the sponge electrodes. When using saline soaked sponges, individuals often find that the session is not only more effective, but more comfortable as well. Often the tingling or “itching” sensation, which may be experienced when sponges are soaked with ordinary water, can be lessened or even removed completely if replaced with saline soaked sponges.
