Young4us Test Tube Set, 50 Pcs Plastic PP Test Tubes in 16x150mm, 16x125mm and 16x100mm 3 Sizes with White Caps and Tube Rack (Pack of 50)

If you are at all interested in using the included rack, don’t get this set. There are no instructions - not the end of the world as it was possible to figure it out but after that it was all downhill. The plastic side pieces were warped, making it nearly impossible to get the tube holder pieces in place. They got stuck (of course) and when I tried to back them out of the track, they instantly cracked. It only got worse because the broken pieces that broke off in the track were cemented in there and had to be chipped out. Second attempt - I oiled the track and shaved down the tabs that held the lip of the main pieces in place with an X-a to knife and managed to get two in place. The third was a casualty - its lip peeling off from about a quarter length of the piece. Luckily I was mostly interested in the test tubes but being able to use the rack would have been nice. So, to sum up - if you want to actually use the test tube rack, be prepared to do some DIY work to get it barely functional.

Only one broken tube on arrival. Serves my purposes.

Worked perfectly for what I needed

Seems to be worth the money

easy to work with.

Great product and display
