While the SpeedStir is nice for that test I find it really shines for the CA test. It makes it so much easier to tell when the color changes.Next time I re-up on my reagents, I'm definitely buying a SpeedStir. I'm tired of throwing out my arm every time I have to shake the heck out of the sample tube to get the DPD powder to dissolve for the FC/CC test...
