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）

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.

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!

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.

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.

Well, it took 3 months to show up, so I ended up getting one locally. However, when it did show up it is essentially a flar plastic sheet that folds together as a plastic rack that snaps to together (2 pieces.) it goes together easy enough and besically does work. Even though it has drain holes in there bottom of the unit, I ended up gluing several metal strips to the base to prefent tipping over (it's that light weight.) (watch your reagents & metal contact of coures.) Cheap and simple and does the job, but the wait killed it for me. If you don't mind waiting it will certainly do the trick.

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 really like these racks. Once you put them together they are very sturdy. I have other racks of similar design that are more flimsy, but these are quite firm and strong. The holes in the rack fit a 50ml tube well, but with enough room for the tube to easily be pulled out of the rack with no sticking.

I needed something to store oil paint tubes cap-side down and this is perfect! Easy to put together, 50 ml tubes fit without a problem and the design makes colors are easily visable. Will be getting more in the future.

...allerdings kosten die wesentlich mehr. Das Rack ist in sich etwas instabil und die Verbindungen halten nicht so gut. Besser sind die Racks aus einem Guss.

Just as expected

Works great. It ships flat in 3 pieces and you bend/snap it to together. Once assembled it's quite sturdy. It holds 25mm test tubes nicely. I'm using the soda bottle test tubes and they fit, though the caps are a bit of a tight squeeze if you fill the tray.with them. They still fit properly, but you need to do a little bit of jiggling.

Excellent little rack, simple design but does the job nicely. Bought test tubes for it and use it for cuttings.

Après avoir cherché partout un porte tube à essai pouvant contenir des tubes de 20ml un peu plus large, celui va parfaitement. Il est d'ailleurs difficile d'en trouver pour ce format. Pratique, lavable très simplement; un spray avec de l'alcool par exemple ou du vinaigre blanc, il se range facilement. Il vaut mieux le monter une seule fois pour ne pas l'abîmer en démontant trop régulièrement. Le montage est extrêmement simple et le plastique me paraît solide et très valable. Il à été un peu long à arriver, vient de Chine, mais cela vallait l'attente. de plus il était extrêmement bien protégé, avec soin, dans du papier bulle.
