Review on 🔬 Karter Scientific 208U2: High-Quality Detachable Plastic Labware for Effective Research by Anthony Cornelius

I bought two of these test tube trays to store and organize the beads I use in jewelry making. They were a little tricky to put together as there are no instructions in the box, but they slide together really easily once you figure out which is up! They're pretty sturdy for plastic, although I did notice a slight crease down the middle when I filled them with bead tubes. The stand has three layers of holes with the smallest hole at the bottom to keep the tubes stable. The stand perfectly holds 50 round bottom straws! The plastic sides have a finger slot for easy portability. Something that doesn't particularly bother me is the tendency of individual layers to slip or "fall back" making hose removal difficult. Just make sure the tray is upright before attempting to remove the pipe or you could end up with a mess that needs cleaning up like I did! :) Will order again if needed and recommend. A NOTICE. This item is a tray only and does not include any storage tubes.
