Test Tube Rack
Blue plastic test tube rack, about 8" long x 2-1/2" wide x 3-1/4" tall OA. It has a plate with (6) holes for full test tubes, the end two being 1-1/16" dia the others 3/4" dia. In front of this are (6) pegs to hold clean inverted test tubes. It of course can be used to hold tools, drying pasta or other, non-lab objects.

Glass Hydrometers & Jar
Hydrometer A is 10" long and is for liquids denser than water, measuring specific gravity from 0.8 to 2.04 in increments of .02 and potential alcohol or Baume between -2 and 73 in increments of 1. It's calibrated to be used at an ambient temperature of 20°C/68°F. (Handy if you're fermenting your own happy juice at home.) Designed to be used at ambient temperatures of 15°C/59°F. There's a third scale in Chinese that probably measures the same things, but our Chinese is a little rusty. The jar (which is unmarked and would make a very slick big bud vase) is 50mm dia x 305mm tall with a 100mm dia base and will take a #10 rubber stopper (not included) if you feel the need to stopper it.

Un-Bunsen Burner
So you don't have a gas jet in the garage? You don't think Margie and Ted are old enough to handle the high temperatures of a Bunsen burner? Our alcohol lamps are the answer. They burn alcohol (available at the hardware store), and are hot enough to boil water, to soften glass tubing for bending, and to generate the chemical reactions generally called for in science projects. The lamp is 2-1/2" x 2-1/2" x 2-1/2" glass bowl with a wick assembly that brings the whole to a height of 4-1/2" and comes with a handy little metal lid/extinguisher.

Färbegestell
Means "staining stand" or "color rack" in German, and we think it's some sort of lab gizmo, but in English it translates to a nice, heavy glass dish 8-5/8" x 5-7/8" x 2-1/8", with a 1/4" thick wall. It comes with an adjustable, rectangular metal frame, 6-1/2" to 11" x 2-1/2" x 3-1/8", that fits over it. The dish looks suitable to bake in to us, and carries the Assistent logo. It's certainly a good serving dish, and with a few rubber bands the rack could be a watercolor brush stand/cleaner. Or you could open a German staining lab.

Teeny Tiny Tubes
Oodles of tiny clear glass tubes. Open on each end, they'll work wonders when connecting rubber tubing or sticking into stopper holes (#27918 is especially perfect for that). Flint glass, so nothing too hot, OK?
