Circuit Breaker/ Alarm Assembly
Tied together are (2) 15A @ 250 VAC breakers that trip on 18.8A and (1) breaker that trips on 10 VDC One of the (2) 15A @ 250 VAC breakers has an integral NO/NC microswitch arranged so that when the breaker trips, it is too, which could be useful to trigger an alarm or warning light. Although mechanically ganged, the breakers are electrically independent. You can ignore the load breaker and use the other two or even just the one with the integral alarm circuit.

All The World's A Stage
...and we are merely microscopes? Develop your own (better) metaphor with this solid black plastic microscope stage, 5" x 4", another fine product from the old Soviet Union. With a 1-7/32" dia hole in the center and a threaded 1/8" dia hole straight through, and (4) threaded holes (Also 1/8" dia) on the underside for mounting the iris and condenser assembly.

Strong Stuff
Filament tape for closing boxes and envelopes that you want to stay closed. It has fiberglass strands embedded lengthwise in it which makes it very hard to tear by accident. You get 10 yds of the stuff, 3/4" wide, in a clear plastic desk type dispenser.

Lab Stand
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. The Burette clamps have wing nuts so they can be adjusted to any angle. The single clamp extends 4" from the rod, with rounded, uncoated, adjustable metal jaws with spring tension and a wing nut. The double clamp like it has rubber-coated jaws. The 3" metal support ring holds the 6" x 6" heavy-gauge steel-mesh burner screen with crimped edges. Nice, solid equipment at a rare price.

Positioner/Holder
A fine concept and pretty successful execution. Weighted bases hold fully adjustable clips and lenses for delicate hands–free work. The Helping Hand w/solder has a 2” high base connected to (2) alligator clips via (3) universal joints and a 4–1/2" sliding beam, and to a 2–1/2" dia roughly 3X magnifier via another universal joint on the sliding beam. It also adds a holder for your soldering iron, plus a hole and thumbscrew in the base to firmly position it. The larger Work Stand has a 3–1/2” x 4–3/4” stand with a 2–3/4” square x 3/8” deep reservoir to hold small parts, an L–shaped sliding beam with (2) alligator clips, and another L-shaped beam with a 3–1/2” lens, about 4X magnification. Joints adjust every which way. The set screws can all be hand–tightened, but we suggest a small pliers to secure the hefty 4X lens. Think of the clips as extra hands to hold wires, components, beads, what-have-you while you perform some operation on them with your own two hands.

Slide Show
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 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.

Magnif Lamp
Magnificent magnifier lamp! Great for hobby work, stamp or coin collecting, needlepoint, sewing and crafts, even reading if your eyes are "mature". The plastic "head" assembly has a 3.5" dia, 3 diopter magnifying lens and a socket with switch for an incandescent lamp (60 Watt max.) This is mounted on the end of an arm the other end of which clamps to the table top. The arm has (2) roughly 15" long sections and swivels at the clamp to allow precise positioning over your work.

Rotary Tool Set
Not every well-made rotary tool is a big-D. We consider this one not only a good-quality tool, but an excellent buy. The fitted plastic carrying case 12" x 8-1/2" x 3-1/2" contains not only the 120VAC-powered 8,000-30,000 rpm mini grinder, but a stand with a C-clamp to mount it on a bench or table, a 3-ft extension shaft, and a good assortment of bits, grinding stones, cut-off wheels, etc, including collets to fit 1/8" and 1/16" bits. The telescoping stand extends from 10" to almost 22" and holds the tool above your work, while you grind, sand, cut, etc., with the tip of the convenient, easy-to-grip, flexible extension. A nice package, and a very nice gift for yourself, or for anyone who enjoys working with hobby tools.

Camera Tripod
A tripod with true portability -- It weighs only 2 lbs; the 4-ft aluminum legs (which can be locked down independently at any length) telescope to a convenient 22", and it slips easily into a zippered black-nylon quiver. The mast, which has a standard 1/4-20 camera mount and a built-in level, can be cranked up (literally) another 9-1/2". The manufacturer doesn't say how much weight the tripod will bear, but we'd keep it to under 10 lbs. Very nice for the money.
