Baby Blue Bottles
Or maybe they're azure. These 2" high, 1-5/16" dia. 1 oz. bottles look a lot like 35mm film canisters, but they have red or green screw caps instead of the hard-to-pry-off caps that film canisters usually have. You can take the lids off these containers without sending map tacks flying across the room. Got a few screws loose? Load your own bulk film? You could use some of these.

Mini Mandrel
Steel mandrel, 1/8" dia x 1-3/4" long. It has a slot head screw fastener with a fiber washer and can handle cutoffs etc with as little as a 1/16" bore and as much as 1/4" thickness. Good for the cutoff wheels you will find listed nearby and similar items for your rotary tool. PLEASE NOTE: In our catalog the size is listed as 3/32". This is a misprint. The correct size is 1/8" shank. Sorry.

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.

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.

Alien
This sinister device seems at first glance to be an innocent ping-pong ball. Touch both of the metal strips on the weighted bottom, however, and a circuit closes, making the ball flash red and moan eerie electronic sounds. Can be used to illustrate the idea of an electric circuit to children-show how electricity can flow through a chain of people holding hands, or that a little dampness can improve conductivity, et cetera. Powered with two watch batteries (included) so there is no danger of shock.

A Gripping Tale
What a cool little clamp! Only 8" long overall, the jaws open to 4" when you press the release button and close incrementally as you pull the trigger. The 3/4" x 7/8" pads on the metal-and-plastic tool won't mar the surfaces they're sandwiching. Makes you want to find something to clamp!
