Here is the link for the stir bars: http://tftestkits.net/Magnetic-Stirring-Bar-1-p68.html
I order 1 of these for chlorine only: http://tftestkits.net/Graduated-Cylinder-Chlorine-only-p22.html
And I think 3 of these for everything other than chlorine so I don't have to wash the cylinder in between samples:

Crackerjack, do the littler cylinders not come with the test kit? If not I am going to order 1 for chlorine and 3 of the others like you mentioned.
