API Replacement Test Tubes for Aquarium Test Kits 6 Pack Bundle

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 !

These replacement tubes are identical to the ones that come in the API master test kits. In my photo is one that came with the master test kit and one of the replacements from Amazon set side by side. Honestly, by the time I had taken the picture I forgot which was which. If youre prone to clumsiness like me or just want more tubes these are a great purchase. They arrived packaged extremely well for transport and none of them had any flaws.

Came in crappy packaging but surprisingly unbroken. Ill probably reorder next time I break them.

Product was a lil on the pricey side and extremely poorly made. Lids leak, and 2 have already broken within first week.

If you need extra test tubes they are the same EXACT ones you receive in any API test kit. EXACT SAME. 5ml Line and everything.

I honestly cant even tell the difference between the original and replacement tubes. The picture is me using them while testing my cycling tank.

I got these because I broke some of my other tubes. Would recommend

These were shipped with no box, even though is box is shown. Fortunately, none were broken, but that should be made more clear.

These are the exact ones that come in the test kit. All arrived intact and well wrapped

First of all, they came packaged super well. I was a bit concerned about ordering glass through the mail, but they showed up in perfect condition and securely bubble-wrapped. I thought they were a great buy for the price, especially since I was considering buying another API kit just for the tubes. I bought my original API kit a couple of years ago and it seems every few months I would drop and break one the test tubes, usually cleaning them. Something else I thought worth mentioning, in the photos, you cant tell but they do have the 5ml line on them like the tubes from the original kit.
