6 Place Plastic Test Tube Rack
by United Scientific

With six (6) openings 25mm (1″) in diameter on the top plate to hold test tubes securely in place and wells on the bottom to keep them from sliding around, this polyethylene test tube rack comes unassembled, though assembly is easily accomplished in just a minute or two. It measures 24x7x9cm (LxWxH), and includes drying pins on which cleaned test tubes can be up-ended for drying.
