API Replacement Test Tubes for Aquarium Test Kits 6 Pack Bundle

Exactly like the ones that come with the API master test kit

I accidentally broke 2 of mine by dropping it. I ordered this and they were exactly the same as my current ones.

Caps dont seal. Leaks when shaking

Good replacement tubes. Unfortunately the test tubes are easy to break. Fortunately, you can buy replacements!

I finally broke enough to need replacements and these were perfect!

Work for what I needed, aquarium testing. They are glass, so fragile, old ones broke so I needed these. They were a little on the expensive side. Whole API test kit is $25 and comes with 4, these are almost $11 for 6.

I have multiple tanks and never seem to have enough of these test tubes. I trust their accuracy. Many knockoffs have round bottoms, which is not at all helpful. If you need or want more test tubes for your water testing, I see no reason to search for another brand.

They came in a plastic bag and 1 was broken. The picture when you order shows a set in a box and thats why I bought them thinking it would avoid the hassle of returns if shipped without protection.

So I got these because I broke one of the 4 I got in my kit, that being said the glass tubs are really nice, but when we get to the caps there TRASH!!!!!!!!!, I don’t no why they would put these caps on them, my biggest problem is that in the test kit there’s ACID! in some of the bottles we use to test and we have to shake them up, and because the caps are trash the liquid comes out when you shake it up. That’s not safe at all and I really think they need to fix this ASAP!

Exactly the same tubes you get in the kits. I was a little worried about shipping because they came loose and alone in a bubble mailer. But they all arrived intact.
