    US Plastics sells everything plastic including volumetric cylinders. Plastic should be fine and far less breakage and cost than Class A Kymex glass etc.

    No need for chemistry. You are just matching colors. Have you ever used an aquarium test kit? If you have, then follow the directions above.

    Wast curious hlow long you could keep these calibrations on hand, store them where and in what? Or just pitch and do it the next time you want to calibrate, be nice if they could be bought pre made at the LFS. Course I would lose the opputtunity to run all over town looking the accoutrements, could not find test tubes with those cool black rubber stoppers or a test tube rack......
    Can't wait to play.....
    Thanks Jason in STL

    It would be really nice to have this information on the first page :) I had to hunt it down. Its valuable to less experienced people like myself.

    Well i made the NO3 solutions, tested them with my NO3 test kit from JBL, and the 50ppm solution gave me a 5ppm on the test kit lol

    Or that test kit is severely off or i made an error on the concentrations,

    Both 50ppm and 10, 20ppm all give me similiar colours, only 50ppm is somewhat more dense colored..
    Gonna make another solution to be sure i didnt get the dosages wrong,

    If i use http://rota.la/ calculator, and make a strait 50ppm solution, would it work, isntead of doing the 1000 and 100 solutions?

    Someone asked whether the reference solutions will change colour. The answer is yes. For me, at least. After some time, all my reference solutions became the same colour. It might have to do with the way I stored them.
