BIPEE Plastic Test Tube Rack, 60 Holes，Test Tube Holder for 17 mm Test Tubes, White vial holder, Detachable test tube holder rack (1pcs，60 Holes）

Use it as an inexpensive RDA and RDTA stand. Cut out top shelf on 12 spots in two rows from center out for shorter items. Kept all 3 end rows full height along with the back row which holds Gorilla 30s and 15ml glass. I did drill centering holes for the bottom 510 pins so the Atomizers stabilize. Not beautiful like easy to scratch acrylic but also not expensive and can be used in the dishwasher. Bonus that the bottom is perforated with square holes to drain and is slightly elevated on bottom by 4 small molded in feet. Comes flat with fold and snap assembly that is easy to tear down. also have the 3 row 21 hole 30mm version. The holes are square so easy to clip some bars out and resize. Able to store 30mm bottles and in 4x enlarged holes 2 ea very large 3 and 4 18650 TC mods each or multiple 60ml bottles and 2 18650 or 20700 TC Mods.

These are great for my single dose coffee vials. I way them out in bulk and use the rack to hold them in the freezer. Before I bought this they were just rolling around on the freezer shelf. Now they are organized and take up less room!! They are cheap and easy to pop together and clean. Seems like they will last a long time too

I bought my first one to use for draining/drying components of my milking machine. It does a fine job. I did order 2 more to use for actual test tube racks, but my tubes are a bit smaller (20 ml) and they tend to lean over to one side. Easy to put together and fairly sturdy.

Honestly, I only bought one of these racks to begin with. I read the description, and looked at the pictures, and decided that I didn't want to waste too much money on a terrible rack. Well... I had to buy 3 more. These racks are great! They're lightweight, but they are still sturdy and hold my tissue culture tubes wonderfully. I can easily use the rack with one tube, or full capacity, and it doesn't seem to make a difference to the rack's stability! The only possible downside to some is it doesn't hold your tubes in a tight upright angle. Your agar will have a slight slant if you care. I don't for what I do though! All in all, great racks for 25mm tubes!

Came unassembled but easy to do so. My main problem was that the grid this too tight to accommodate test tubes with any kind of a ridge or lid. Putting a full set (24) means some will be above the rest.

I needed an extra rack to hold tubes for milkweed cuttings that I collected for the monarch caterpillars I was raising. This rack fit the 60ML tubes that I had on hand great. Makes it so much easier to feed the caterpillars. I clicked it together fine on the first try. It has not come apart.

Since I already had several floral tubes and needed another rack, this was exactly what I needed. Some people griped that it didn't stay together after snapping it together so before I began to snap it together I pre-bent all the sides. Once they pretty much stayed in place I then snapped the middle and top pieces together. To make sure it stayed together I placed a rubber band around the outside near the top.

Holes are too big for test tubes to stand up right! They are leaning. I have some coming from Temu that are perfect and half the price!!!
