3 pcs microcentrifuge Tube Rack lab centrifuge Tube Holder Stand lab Test Tube Pipe Holder with Double Panel 60 Wells for 0.5ml-2ml Centrifugal Tube

I found these after perusing a tool forum for alternate bit holders. You know - the hex bits for screwdrivers.These are (almost) perfect for this alt use. They are just a tad tall, some bits need needle nose to pick out.They stack well enough, but I have these now in the drawer of a tool chest laid out for easy identification.Good alt use !

I am impressed with the quality of these holder. I am using them to hold my ammo while I am reloading them and they work just great. The space between holes is wide enough to put my fat fingers around every round. Extremely pleased

I actually bought these to hold my many fragrance sample vials and works great. They have a nice weight to them and are made very sturdy. I also like that they're double sided so you can hold multiple different sizes of vials.

I’m disappointed that this test tube rack didn’t fit my API Freshwater testing kit tubes. These racks are very sturdy and it is nice that it has two different sized slots, the larger on one side and the smaller on the other side. The different colors are helpful for differentiating between different types of colors.
