Glass Test Tubes with Rubber Stoppers 150mm x 20mm Pack of 10 and 1pcs Brush …

Great quality and value

These test tubes are perfect for most things you would need them for. They are medium sized.They are sturdy and reusable; the glass isn't too thick but its not as thin as other tubes.Admittedly, I was worried to order something like this online but I couldn't beat the price.The contents were well-packed and nothing arrived broken!The rubber stoppers were stuck to the glass as if they were in the tubes for a long time.This wasn't a problem because I could spin the tube and unstick the stopper before trying to pull it out.It's still a snug fit and will work perfectly for my needs.The best thing that surprised me was how clean they were.I'll still rinse them before use but I won't have to run them through the gauntlet.

I do ant keeping so I bought this and it works really well but the thing it comes with to clean it smells terrible when it gets wet but cleans it good

These are nice

The media could not be loaded.  I use these tubes and magnets that I also bought on Amazon as my propagation station! It has been incredible!

So far very impressed. My mailman threw them down On the concrete porch and they did not break, was very thankful. Cannot wait for science experiments.If I have a negative the stoppers reminds me of the spray foam.

The product arrived on schedule and the packaging was very sturdy. Unfortunately the first tube I used the bottom leaked and cracked right off like it had been cut. I have not used all of the tubes yet but the other two I have used are okay so far.

Perfectly fine test tubes. The glass does not respond well to cooling after reshaping, just FYI.If using a syringe make sure to have long dispensing needles.

I like the quality of the glass test tubes, and the fact that they come with a cleaning brush. But unfortunately the rubber stoppers leak from the middle and stain as seen in the photos. Can't use any of them and had to buy a pack of corks separately before I could use the tubes at all. But if you're not planning on shaking up the contents or tipping the tube upside down, then they should suffice.
