6 Pack 28 Well Test Tube Rack, Laboratory Centrifuge Plastic Tube Holder, Detachable Plastic Stand, Storage Test Tube Rack for 10ml / 15ml / 50ml Tube, Blue and Orange

Holds 50ml and 15ml conical/Falcon tubes well! A little flimsy but good for storing tubes in the fridge

Great price, easy to use and assemble, holds plenty of centrifuge tubes with ease. Rack is stable and fits 50mL tubes well. For the price, I would purchase these again.

They are a solid product for the price. They held multiple sizes of our centrifuge tubes. They were great for science experiments and easy to assemble.

Simple and worked. I had to assemble them, but it was very easy. They're plastic and breakable, but not too flimsy. None broke during the party. And you can take it apart and store flat. Great in my book.

While these are made for certain things, I purchased them to use for my milkweed cuttings for my monarch butterflies. I plan on using a flower dropper in the slots meant for the test tubes and I will put the milkweed leaves upright inside of them. I have not officially used them yet but I found once assembled took a little bit of tweaking to determine which side goes on the inside and which goes on the outside. The holes are tapered and while conceptually I understand why, the items didn't sit flush once inserted on the tapered side so it could just be that it's because I'm using them for a different purpose than intended. Either way, they are not as sturdy as expected and I feel as though I will snap them if I continue connecting and disconnecting them from each other so keep that in mind

The test tube holders are too short.
