A great thing to have around for electrolysis experiments or if you want to try a carbon arc. High quality and inexpensive.
We used this for Physics in our homeschool. Awesome price and it worked great. I always worry about this sort of thing arriving in one piece but it did thanks to the awesome packaging we can always count on from Home Science Tools!
Useful in Electrolysis
I have always struggled to find good electrodes to use when I was performing an electrolysis of salt water since the chlorine formed is highly reactive and corroded many of my electrodes. I have been impressed with how well these graphite electrodes withstood the corrosive chlorine.
