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.

Inside the lab, it's a standard translucent-white, LDPE-plastic wash bottle, 500ml/16oz, measuring 2-3/4" dia x 6-3/4 tall with a screwcap and a right-angle, 5/16" dia nozzle. Outside the lab, it's so pleasing to squeeze and squirt with that some of us keep them in the kitchen.

Assembled in the U.S. from Russian parts, anyway. What we have here is a full range of sizes in gas masks for children, although frankly, the smallest of them are really more Yorkshire-terrier sized. New, but surplus, and while they're rated NBC for nuclear/biological/chemical contaminants, they carry absolutely no guarantees. These are to be used as part of a collection, or for costume/novelty purposes. The children's masks come with a 12" long hose, filter tank, defogging pencil, and carrying pouch. The Small is for faces less than 4-1/4" between cheekbones (and less than 3" from the top of the nose to the chin). Medium is for 4-1/4" to 4-1/2" (3" to 3-3/8" top of the nose to the chin).
