I have an API test kit and the test tubes do not seal well. They leak when I'm shaking them. Can someone recommend an alternative?
I use the SR Aquaristik Speed Test Kit Mixer which comes with short wide vials and lids, however with this mixer you don’t need to use the lids as the magnetic stirring can be controlled so that it does not splash out. The vials even have a 5ml mark on them just like the API ones so there is no issue using their chemistry to complete your tests. Works great for me!I was bad at breaking the test tubes and came across these at Michaels. Glitter shakers, 6 for a buck and some change. I'm sure any craft store, probably Wal Mart would haveView attachment 447668
