API Replacement Test Tubes for Aquarium Test Kits 6 Pack Bundle

Luckily the tubes arrived in tact but as I unwrapped them I totally expected them to be broken. They were tightly wrapped together in a layer of bubble wrap but loose in a much too large Amazon box. They appear to be original API tubes but I much would have preferred the box shown in the picture for safe storage.

Can always use extras for multiple tanks!

The caps are kind of big so the water spills during shaking

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.

Every thing seemed good! Was just expecting better packaging! But they made it safe never the less. And I just think their pricey for what it is! They only got the sale because I needed them!

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 !

Exactly what I ordered. Same as test tubes that came in the master kit. Only problem is they were poorly packaged and one was crushed. Other 5 were fine as far as I can tell. There was some protection on the top of box but none on bottom or wrapped around the tubes. Very surprised since these are glass and very fragile. Shipping was fast so that’s a plus.

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

Tubes came all in one piece and I can now test multiple chemicals at one time for my salt water tank. Prior to this I only had one tube with my master test kit and needed to do each one separately.

They came as described and also delivered a few days early. Very happy with my purchase.
