Open it is just under 2 ft long including the swivel head, perfect for fishing under the radiator, in the depths of the bilge or at the back of the rattler's cage.

Litmus Paper
Chemically treated paper strips to test for acid or base (alkaline) solutions. Use the blue for acids, the red for bases. The more sophisticated pH test paper strip indicates pH from 1 (bright red) to 14 (dark brown). Values in between can be read by comparing with a color chart that comes with the strips. All have (100) strips of test paper per vial.

Test Tubes!!
Test tubes, culture tubes, there doesn't seem to be a standard term for these standbys of every lab. The plastic tubes are 10 mm in dia. and 75 mm long. The glass are all flint, which means you cannot put them over a flame or heat anything in them. The assortment of glass tubes is from 10 to 14 mm dia x 50 to 100 mm long. We'll give you the best mix that our supplies can produce. Chances are you'll get all of one size in each order.

Mashers and Smashers
Porcelain mortars and pestles. Great heavy duty mortars, with sides that are easily 5/16" thick on the smaller ones, and up to 1/2" on the larger. The mortars are glazed outside, but rough inside, the better to grind, and have a pouring lip. The business ends of the pestles are unglazed, while the shafts are glazed. Very functional, very good looking!! So grind your own spices or lab concoctions as you prefer. You get a mortar and pestle as a single order.

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.

Double Vision
A clever twin-lensed loupe that clips on eyeglasses for hands-free magnification. Each 1" dia, 3.3-power glass lens is at the end of a thin metal arm and swivels easily. The metal clip mechanism is about 1-1/2" long, each lens and arm about 2-1/2" long. Use a single lens, or line two up to double the loupe to a 6.6 power. Individually, each has a 3" working distance. When they're used together, it's 1-1/2".

Elemental Information
Holy Gadolinium, Batman, who discovered this Gd element? We're not sure, but he's close to our hearts, since Gd is a magnetic metal of the rare-earth group, and you know how we love rare earth magnets. This excellent 38-1/2" x 26-3/4" poster of the Periodic Table lists the elemental information about Gd and 117 other elements, and includes mini-biographies of (7) scientists. The full-color poster is not laminated, but is a good quality coated paper, and a fascinating addition to any classroom.
