Newly manufactured P-38 Can Opener from the same folks who supply them to Uncle. It folds! into 1-1/2" x 5/8" flat piece which is easily carried and lost. Reportedly works much better than the Asian knockoffs for those who really want to gain entry to the Spam!

...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.

Microscope glassware for examination of blood, pond water, mold, and other minutiae. All of the microscope slides are optically clear glass 26mm x 76mm (about 1" x 3"), between 1mm and 1.2mm thick. The well slides, of course, have a concave well to hold a drop of liquid. Our each is a package of (12) well slides, or a box of (72) standard slides with ground or beveled edges. Cover glasses are the smaller and very thin pieces of glass used as the top of the glass slide sandwich. They are often used temporarily by simply dropping them onto a drop of liquid to flatten and spread it and to minimize evaporation. More confident microscopists will cement them in place to permanently preserve a specimen. Our each is a package of (100) cover glasses 18 mm square, #1 thickness (0.13mm to 0.17mm). If you need one, you need both.
