API Replacement Test Tubes for Aquarium Test Kits 6 Pack Bundle

Absolute game changer if you have multiple tanks. You can allow one tank’s test to process while you begin the next test instead of waiting before starting the next tank. Simply noted the time and move to the next tank.

I had ordered these to replace some test tubes and to have back ups, but upon arrival two of the test tubes were completely shattered, unusable. Another two were chipped and just this morning one of those shattered while placing the cap on. Im not going to use the second chipped one because its just to end up completely breaking. TL;DR I ordered 6 test tubes, and I received 2. Manufacturer packaging was intact and bubble wrapped, no apparent damage to the box it was delivered in.

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

The test tubes came in on schedule. None was broken in transit. Was packaged nicely.

Theyre the same exact ones that come in the test kit. I just find it so annoying that they break so easily when trying to get the cap off. You have to be super careful because the cap starts to grip the glass tightly after a few uses, and if you squeeze to hard, the glass breaks in your hand. Ive learned to be ultra careful and gently twist back and forth. Im very petite, with small hands, and Ive definitely drawn blood a couple times after breaking a tube (its fun when you break a tube of chemicals into your hand). Not a good value if they break so easily. Use at your own risk.

Good to have I case others break. Like others have stated. They didn’t come shipped in the box as pictured. All tubes was received without damages though.

They are the same cheap glass that shatters at the slightest pressure . Wish they would use Pyrex or at least some glass less prone to break !

Api test tubes

Perfect replacements . Good price

Absolutely love the packaging! The vials are great value for what I paid. They even came with a chart on what the tanks numbers should look like.
