Would an agitator be good for mixing test tubes?

Would an agitator, like this, be good for mixing test tubes. Standing around shaking test tubes is sort of a pain. It seems like this might make things easier, or it might potentially introduce air bubbles which might distort a sample. Any thoughts?

What kind of test kit's do you use? I know salifert kits always say "swirl gently don't shake" I assume because air bubbles could effect the results.

Try a magnetic stirrer instead

I have this one and it works with red sea test vials

I agree it may depend on the test, but for, say, alk or calcium or magnesium it would work well, if not being overkill.
