Macro-Case For Microscopes, Plus

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.

Pill Box

This thin-walled vial is shaped like the one your drugstore prescriptions come in, but since it doesn't have a childproof cap, it's a lot easier to open. It's lightweight clear plastic, 2-13/16" tall x 1-1/4" dia, with a white-plastic cap that fits snugly into the top. Holds approx 2 oz. Nice for pills-or paint samples, medications, field trip artifacts, crime scenes, electronic parts, spices, that whole crowd.

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.
