Tube (Et Al.) Rack
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.

Litmus Paper
Chemically treated paper strips to test for acid or base (alkaline) solutions. Use the blue for acids, the red for bases. The more sophisticated pH test paper strip indicates pH from 1 (bright red) to 14 (dark brown). Values in between can be read by comparing with a color chart that comes with the strips. All have (100) strips of test paper per vial.

Blue Tubes
Well, centrifuge tubes with blue screw caps. These are your standard 15ml plastic tubes, 5" long x 5/8" dia with tapered bottoms (unlike yours) and 0.5ml graduation marks. Not a centrifugal person? These are dandy ways to transport liquids in 1/2-oz quantities in your shirt pocket.

Latex-Free Gloves
These clear-plastic latex-free gloves, called Express" Gloves because they're big and flat and much easier to don than standard latex, are a pretty-much one-size-fits-all 11" long. You get (3) compact, re-sealable packs of (30) gloves (45 pairs-we do the multiplication so you don't have to). Dandy even outside the lab for food prep, pumping gas, painting, icky baby clean-ups, unspeakable dog-walking chores, and worse.

The Men In The White Coats…
They're coming. Women in white coats, too. They got them here, and said they were a steal. You choose from disposable, water-resistant lab coats, sizes Medium (36" long), XL (38-1/2" long) or 3XL (41" long), all with snap closures and waist pockets. Or the disposable, water-resistant coveralls, size XL (62" long) with a zippered front and elastic cuffs.

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.
