Plastic Test Tube Rack, 24 Holes?Test Tube Holder for 25 mm Test Tubes, White Vial Holder, Detachable Test Tube Holder Rack (1pcs?24 Holes?...

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.

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 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.

These were purchased to hold small bottles during a filling operation. They do this task perfectly and allow easy transport to the next operational step. Assembly takes a fair amount of strength to snap together, but once together, they are strong.

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!
