Made from dark oak-stained pine, this 2-tier test-tube rack is ready for the lab, particularly if your lab has a 19th century look, but it would also make a dandy spice rack if you pop for test tubes with stoppers. If you're more creative, consider a linear flower arrangement, pipes, brushes, markers, pens or anything else that fits. Stands 8-1/8" tall x 10" wide x 3-3/8" deep with (6) 2-3/4" x 3/8" dia drying rods, (6) 1" dia test-tube ports, and (7) 3/4" dia ports.

It's made for holding a microscope, but it's a fine large carrying/storage case with endless possibilities. In navy nylon with grey straps, it's 18" tall x 11-1/2" wide x 8" deep with (4) small feet on the bottom so it stands upright. The straps extend beyond the top to serve as handles. The whole case is foam-padded, with a couple of hook-and-loop straps for securing whatever is inside, (2) elastic pockets in the lid for accessories, and a zip closure around (3) sides. Fits most microscopes, but would hold any number of things, from electronics to dinner-to-go for six, and would be a very nice way to organize assorted stuff in the trunk or back of an SUV.
