If you start with the plunger down at 0 and pull it back to the 1ml mark you will have 1ml of fluid in the tip. The tip holds slightly more then 1ml of fluid.

Used my HI-755 for the first time last night, hoping I was successful.
I was able to draw reagent into the tip and all the way to the 1.0 ml line with the plunger pulled almost all the way out. I guess we do draw reagent just barely into the syringe itself, correct?
Got a reading of 173 * .056 = 9.688 dkh Guessing that based on the product review posted originally by Boomer, and not having compared the results with any other test kit, that it is possible that my reading is a bit high so can I safely assume that my alkalinity is around 9 or so?
Also, rinsed the syringe and tip thoroughly in RO and stored for next test, any other suggestions for having clean syringe and tip for next go?
Thanks,

Ok I have the tip fitting tight, and the reagent is no longer leaking back out on its own, but the reagent still only reaches the top of the tip where it attaches to the syringe and dose not enter the syringe. Is this correct or should the reagent also go into the syringe a bit? I want to make sure I'm using the correct amount of reagent
I had an old one laying around so I used water with red food coloring in it for and example of how it will look. Just always remember to push the tip very tightly on the syringe and pull the liquid very slowly from the bottle.
Thanks Sport, That is the level I was getting. I was not sure it was correct. After talking to the Hanna CS. guy today he said that as long as you pulled the plunger back to the 0.1 mark you would be getting the 1ml. of reagent, and after a few tests I see that the reagent dose not enter the syringe. But a picture is worth a 1000 words. Thanks for your effort I'm sure it will help others also. I seen your post, that said your Hanna and Salifert tests are about the same. Have you crossed ck.ed them a few times? The Hanna seems easy to use if we know the read out is correct.
so is the general consensus that the hanna alk checker reads 18% high as reported?
or does more testing need to be done.
