Steve Spangler's Large Plastic Test Tubes & Rack, 6 Bottles & 1 Rack

The stand is just the right size and easy to assemble. The tubes are sturdy plastic and the lids screw on like a 2L soda bottle. Which is great when my son mixes things and shakes the tube to watch it settle again over time

Shatter proof. My son dropped one from his hand filled with whatever concoction he needed for his homeschool, and it was durable enough not to break. He has done several experiments, and they have held up so far.

Product itself is nice. Tube seems substantial and rack is functional (a bit wobbly, but not a big deal). Packaging however is terrible! Arrived in a an envelop instead of a box thus tube was chipped just like another reviewer’s photo! So annoying!!

I needed test tubes for water samples for a college level class. These were perfect, so much so that the instructor kept my project for his office. Very easy to use, sturdy, the stand holds everything perfectly and it is just a very well made product. I recommend.

I used this in my classroom (science teacher) to hold tiny, fuzzy spheres that different class periods could earn in classroom competitions. It was nice to have a rack to display the tubes so the students could see their progress.I did not use them for experiments or other similar activities.

Super cute and it comes with experiment ideas. The tray could be a little sturdier but I’m happy overall

…and a bottle connector. This allows me to fill one side with perioxyl and my brush sits contained in this bath, inside my shower. My gum health has improved considerably.

I assembled it to make sure it worked, then went to disassemble it and part of the plastic frame broke. It still works so I'll keep it, but I won't but this brand again.
