I am so happy with this API ammonia test kit purchase xD

Not actually kidding. I like to use the API tests. Originally I thought they were kinda lame, but turns out the issues with them is overblown.

Anyways that's not important. Why I am happy is the cap on this vial is the one that prevents water from escaping the vial while shaking. My master test kit and this kit has this cap, but two other tests has a terrible cap. Though they all seemed to have been made in the U.S.

So now, proper question: anyone have any idea why there is the two different types of caps? And how do I make sure I can get the vials with these caps?

I had four before and broke one, luckily this will now become a replacement. But I'd like more. I like to do serial 1/2 dilutions down to 1/8, so I do need four vials.

Contact API, they might be able to help. Or check at a laboratory supply shop online for the test tube and caps
