The Paragon
...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.

Jar Vase Beaker
It's a forceps jar, for keeping your forceps' teeth sterile, but if you happen to be forcepsless, it's just a clever jar, juice glass, vase, beaker or container thingy.

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.

Test Tube Tongs
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.
