To meet all of your little plastic test tube needs. They're 13mm x 100mm plastic test tubes (approx 1/2" dia x 3-15/16" long) and will hold 7ml and take #2 or #3 corks, (#2 is a better fit) which aren't included. The bulk price also means you can make endless little vases for keeping flowers fresh in corsages, construct futuristic light fixtures, transparent sculptures, strange centerpieces, whatever. Use your imagination.

Clamps. Whatever. These measure approx 5" long x 2"' at their widest. They open to about 3", though, so they'll not only grab test tubes, they'll pluck cubes from an ice bucket. Or carry a few stems of asparagus. And you do get a pair, so you could always have a tong war.

Made from pine and treated to be fluid resistant, 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.

Distillation made heuristic. Nothing explains a process like a little hands-on experience, and this laboratory distillation kit is for showing instead of telling. Includes a 300mm Liebig condenser, Kjeldahl distilling column with 50mm dia bulb and rubber stoppers, 500ml Bomex boiling flask with 8" iron tripod, 2-foot lab stand/base with a single burette clamp, 500ml graduated Erlenmeyer flask and a 6" square of ceramic-coated wire gauze. You add some 1/4" ID tubing for the Liebig ports. Includes good directions for distilling ethanol and acetic acid. And let's remember that this is for laboratory distilling. Don't try this at home.
