Because, you know, you might have broken a few. Much better deal to get the pack than a 3 or a 6.

I have too many tanks and like to test them all at once so I needed more test tubes. Came intact and just the same as the tubes I from the freshwater master test kit.

Two original tubes were broken during the tests. I hope these last much longer. Good price.

They work with the API water test kits, which is all I needed. Took a star off because not all of the lids are leak-proof, which can be an issue for the tests that require shaking vigorously like nitrates.. but all of their test tubes are like that, so oh well.

Needed new vials as my old ones were a bit cloudy. These are perfect and exactly the same as what comes with the testing kits.

Needed more than just the 4 tubes included in the master test kit. This was exactly what I needed!

I broke a few tubes in my API test kit and was very relieved you could buy replacements. These seem to be more solid than the ones that came with the kit, or maybe I'm just more careful now. You get a whole lot of tubes in this box so I don't think I'll need to buy any more for awhile. Very convenient, good purchase!

Pretty good for the amount of test tubes you get for the value but some of them leak when you shake them

The API freshwater testing kit is wonderful. It is just the tubes tend to break if your are not careful. One broke one my son and one on me. Thus I ordered more test tubes. So far these seem to be working out great. The 5 ml marking is nice to have on the tube. Noticed some of the tubes sit a little snug in the API test kit area that the tubes are stored in vertically.Overall nice to have spares on hand.

My son accidentally broke two of the glass test tubes that came with the ammonia and pH test kits. Just when I needed it most, I had nothing. The pandemic made it worse, where Petco and PetSmart were always out of stock. So, I made sure that I ordered a set of 24 in case of more accidents. The glass is not that thick but sheer so that you can make a good color reading which is important. I'm skeptical about using the plastic bottles because I'm not sure how clear they would be to make a good reading. Plus, I prefer glass for the share visibility. I wish the glass was more durable though, because the cleanup SAR another issue, tiny glass pieces can be missed and end up in your Barefoot. Ouch! Overall: good for sheer visibility color check. Value: could be cheaper as glass always needs to be replaced when broken.

These are just like the ones from the kit. I prefer glass for taking readings and these are the correct size for the chemicals in the kit.

Sad these are offered in such a large quantity but luckily I have lots of tests to do. At $0.50 a pop, not exactly cheap but the best price per unit i can find. They leak when shaken, a common thing for water tests. Not good when shaking corrosive chemicals. They do break as they're small and glass, but not entirely frail like grandmas fine wine glasses. The caps pair nicely (minus the leaking) and the tubes can be stood up on their ends. These are OEM, come with the 5mL markings, caps, and everything, but are a bit pricey. Also they leak. Honestly a big turnoff for API tubes.
