Polypropylene Test Tube Rack

Summary: You get what you pay for, Avoid This test-tube rack is the same design and quality as items 470164-054, and 470164-050. I commented on the latter until I realized after scrolling down that I had actually purchased several of these. The rack design is unstable and dangerous. The pieces don't interlock, so the horizontal components have slipped out with the slightest movement of the rack and/or. they rack (become trapezoidal ). Both scenarios have occurred frequently within the first week; not a good thing when there a test-tubes containing microbes. Tried to glue them together with epoxy (which was still less expensive than purchasing a good quality rack) but didn't solve the problem.
