Stethos is Greek for chest. Indeed you can scope your stethos with this stethoscope, or your friend's or your dog's. But it works equally well for picking up any sound being transmitted through a solid medium. Listen to the air flowing through the heating ducts, the water in the pipes, the sounds of machinery, the termites munching on the floor joists!! The color does vary so we will select from what's currently available. We've had blue, teal, red, black, burgundy, green and purple, but there may be other colors yet to be seen! A great discovery device whether for biology or other pursuits. Not of professional quality, but not just a toy.

Sometimes at the end of a long day of typing, our fingers just need to lie down for a while, so we grab one of these finger cots and….sorry, we were challenged to write a clean finger-cot joke. Never mind. These are your standard, natural rubber latex finger cots, aka “sheaths,” size small. Use them to protect your fingers from paper cuts, dryness, chapping, irritating liquids, whatever. Our each is a box of (144). Gross, you say? Yeah, kind of.

We’ll say. Herr Erlenmeyer of flask fame was handled Richard August Carl Emil Erlenmeyer, but you can call him Emil. Our Borosilicate glass version of his flask holds 500ml, and is graduated from 200ml to 400ml in 50ml increments. Stands 3-3/4” tall with a 4-1/4” dia bottom narrowing to 2-1/2” at the top, which also makes it a hard-to-spill coffee cup.

Easy to do, and important these days. We’ve been pointing this non-contact infrared thermometers at just about every forehead we see. Reads in one second with a digital display in C or F. Measures body temps of 89.6 to 108.5 F (32.0 to 42.5 C) with a resolution of 0.18 F (0.1 C) and color changing backlit display to warn you when hot is too hot. Normal operating temperature (ambient air) range is 60.8 to 95 F (16.0 to 35.0 C), and the device should be held between 0.4" and 2" inches from those foreheads. Want to fry an egg on your car dash? Switch it over to surface mode to check, well, surface temps. Couldn’t be easier to use, or more important in times like these. Plus, when this is all over, you’ll never have to stick a thermometer under your tongue, or anywhere else, again. Approved by the FDA as soon as you add a pair of "AAA" batteries.

In the lab or kitchen, these clear borosilicate glass mugs have a handle and lip and remind you that science is part of your every day. The smaller 4-1/2" 400mL one has graduations in 50mL increments and the larger 6" 1000mL one in 100mL increments with numeric markings every 100mL or 200mL accordingly; both with more room before you have to worry about spilling. May come with a pour spout on the side opposite the handle which won't affect your beverage consumption but will make it easier to water your favorite house plant. Not intended for serious lab use as the volumes are approximate. Remember to ask for 236.5ml of coffee the next time you visit your favorite diner.

Chemically treated paper strips to test for acid or base (alkaline) solutions. Use the blue for acids, the red for bases. The more sophisticated hydrion 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.

There's a tool for everything. Think post-hole diggers for a model railroad layout. All right, all right. Think cork borers for all those solid corks and rubber stoppers in laboratories, the ones that need holes for glass and rubber tubing. Our each is a set of (3) 3-3/4" long brass tubes with sharpened ends and red-plastic T-handles. Diameters are 9/32", 7/32" and 5/32". They're nested on the 4-3/4" pin used to clear the plug from the tube.

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 the Burette clamp and the ring attach to the rod with thumbscrew clamps. The Burette clamp has a wing nut so it can be adjusted to any angle. The clamp extends 4" from the rod, with rounded, uncoated, adjustable metal jaws with spring tension and a wing nut. 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.
