The cya viewing tube that came with my Leslie's/Taylor kit was crushed. I ordered a replacement but didn't realize I ordered a slightly larger one! How do I use that one? How much water and how much cya reagent?
You can experiment with it, but I use 14.6 ml of each and it fills the view tube almost to the top.
I use 14.6 because it's marked on the sample vial and I have two of the 9198 vials. I fill one to 14.6 with water and one to 14.6 with R0013 and then mix the two in one vial on the speed stir.
