API Replacement Test Tubes with Caps

The picture is not what I got. What I got was the API testtubes which I am happy with. They are the exact same that came with all the API tests that I already have. And to make your life easier if you have a bunch of these get one of these: "Karter Scientific 208V2 Plastic Test Tube Rack for 12/13mm Tubes, Holds 50, Detachable" Its a perfect fit.

If you use the API test kits then you may want to get these to go along with it. These are simply replacement tubes for the API kit so they are the exact same as what comes in the kit (clear tube with a 5 ml mark and a cap). And since they are somewhat fragile you will eventually need some replacements. Also helps out to have multiple test tubes if you are testing multiple tanks at once, in my case, 6. Its a lot easier filling a bunch of tubes at once for testing than using, rinsing and reusing the same few tubes over and over for one batch of tests.

Since I have four aquaria to check I have found the extra tubes to be very handy and time saving. I can check the water in all four tanks before I have to clean out the tubes I used during the tests.
