Affordable, adaptable lab equipment for serious scientists with laughable budgets. The basic stand is heavy black metal 8" long x 5" wide x 1" high with a 19-1/2" x 3/8" dia support rod screwed into it. Position a beaker or bunsen burner on the stand and build the configuration you need above it. Both of the Burette clamps and the ring attach to the rod with thumbscrew clamps.

...is an inspection and dissection binocular microscope. The manufacturer says it's "perfect for industrial, agricultural, biological and educational uses." We heartily concur, which is why we're stocking this shiny new non-surplus item. "The Paragon" is 15" high, sturdy, easy to use, and has an acid and reagent resistant finish. At 10X and 30X magnification it's not for the weensiest microbes, of course, but if your work is on the scale of distinguishing weevil species, this is what you want. The 95mm dia stage plate reverses white to black for contrast, and the rack and pinion pole mount lets you view samples up to 17 cm in height. The binocular head is inclined for comfortable viewing, rotates 360°, Wide field 10X eyepieces adjust to 55 -75mm interpupillary distance. 1X and 3X objectives are turret-mounted. With the 1X objective, you get a 19mm field of view, with the 3X, a 9.5mm field. In either case the working distance is 95mm. Don't do entomology without it.

What's the opposite of frenetic? This tabletop lamp. The egg shape is soothing, the smooth surface is frosted, and the egg slooowly changes from pale yellow to pale green to pale pink to pale blue.... The open end of the 8-1/2" x 6-1/4" dia glass egg rests in a brushed aluminum base that houses a 10 watt halogen bulb and a motorized color wheel. It's 12-1/2" tall OA. The 6-ft power cord has an in-line switch and terminates in a plug-in wall adapter. Why pay $25. or $30. when you can buy surplus and save money? Now that's soothing....
