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.

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.

    I’ve been using tDCS for a few months now and It took me about three months to slowly work up to the full 2mA setting. I have v II unit I was using was leaving a lot of irritation, even though I made saline solution according to the instructions and some recommendations from reddit. I finally ended up buying this cool squeeze bottle from the Brain Stimulator, which allowed me to increase the stimulation much faster.

    I noticed some small improvements around 1ma, but things really started picking up around 1.5ma. I’ve never been very verbally articulate (I had some concussions awhile ago so I stutter, search for words, use the wrong words, lose my train of thought, etc.) But this has really helped, to the degree that folks are noticing, and my boss commented today that I look “more put together.”

    It’s also helped with memory and recall, organization skills, and paying attention. It’s not just a placebo effect- I can see my work performance has improved and I’m doing better, quicker work. My apartment is also cleaner, I’m getting more chores done, and things just feel easier.

    Also noticed some slight improvements in my writing quality- I write a lot for work, so I can compare my writing from this month to a few months ago and see changes (more sophisticated word choices, writing more clearly, doing it faster, etc.)

    Overall- it was great for me, but I’ve probably got undiagnosed/untreated ADHD, some existing neuro problems, and DX’d anxiety and severe depression. So maybe I had more things to fix, or it’s working differently on me than the “average” person. I intend to keep doing it at the recommended current setting.
