I use a 10ml syringe and draw 9ml + 1ml Reagent A
I am yet to get a reliable measurement in 30 tests and have resorted to a titration kit.

Just a side note, I was advised today by Hanna Rep to use 9 ml instead of 10 ml. Our RODI water may have enough contaminants to alter the test slightly. I'm going to invest the products he is using in this video.
