    What People Are Saying

    Perfect for small bud flowers

  • I purchased 6 test tubes, along with a stand, to be used as small bud flower vases for a friend's birthday and she loves them. She also blends her own beauty products and uses the test tubes when making new formulations. All tubes were intact and as ordered.
    Good Quality

  • We have been using HST test tubes for the past two years. We have not had any shatter when heated.
    Perfect!

  • I bought 4 sets of these for my 2 children. We use lifepac science for homeschool. I had purchased others from another website that were cheaper and they ended up being way to small for what we needed to do. These are shipped carefully and are just what we needed. As I bonus I put them up and can use them in the years to come with other science experiments!
