LAB/SCHOOL

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! Not professional quality, but also not just a toy.

This digital instant-read lab thermometer measures 8-1/4" long total with a 5" long stainless-steel probe that's resistant to most chemicals. Has a removable cover with a pocket clip, on/off button, and C or F readings (-50 to +300C, -58 to +572F). Button-cell battery included.  

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.

This small chrome constricting clamp is designed for controlling IV drips, but no doubt will inspire other uses for crafters, jewelry makers and those who want to control the flow from small pumps both air and fluids. Measure 2" x 1-1/4" OA when fully open. Flat clamp screws open to approx 5/8". The clamping surface is approx 3/4" x 1/4". Uber handy to have around. 

On a slightly convex aluminum plate, with small mounting holes top and bottom. Our glass thermometer measures between -30° and 230°F in 2° increments and between -30° and 110°C in 1° increments. The unit measures 6-1/2" x 1-1/16" with a 4-3/4" long kerosene filled element. Made for educational use, but nicely readable and able to hang on your wall without looking like part of a weather station.

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.

Stainless steel mortar and pestle set. Mortar measures 5-1/4” dia x 3” on a 4” dia attached saucer-like base. Holds approx 250ml. Pestle is 6-3/4” long with 1-1/4” and 2” dia heads. Nice for the lab, or for folks who want everything in their stainless steel kitchen to be stainless steel. You know who you are. And we salute you.

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.

These Periodic Table magnets stick all the time—not just periodically. They’re part of a (128)-piece modern Periodic Table of the Elements set in a 4” x 6” x 1" tin. You know, like “K” for potassium and “N” for nitrogen? Cooking is science, so why not have these magnets in your kitchen? You could also use them to learn about the elements, since they’re based on Dmitri Mendeleev’s 1869 study aid. Completed chart measures 9-3/4" square-ish when arranged, with each element magnet measuring about 3/4” x 1/2”. Feel free to spell out funny words, too—this isn’t your final exam.

Almost big enough to pick up mortals: 9-7/8" long, 1/2" at its widest, with a mouth that rests open at 1-3/16". Stainless steel and non-magnetic, with a rounded serrated tip that's 5/32" wide. Good for giant splinters, crafts, jewelry, electronics, or sushi.

Wanna stir up a little trouble? We've got just the tool. Our solid glass stirring rod is 8" long x 3/16" dia. Flat ends. Perfect for mixing a scientific formula, a perfect martini or a jar of tempera paint.

Puns-R-Us. This white coffee mug has pi-Lingual printed on it, along with a bevy of geometric diagrams and equations, plus pi carried to 50 decimal places. Try not to use while eating a piece of pie, because there are some limits to what people will tolerate.

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.

That'd fill this 9-oz ceramic coffee mug with the periodic table of elements printed on the side to about half a cup. It's printed in color on both sides, actually, in case you're left-handed. The atomic numbers and weights are a trifle small, but then they are atomic.

What a price for a Sprague Rappaport stethoscope! And the improved model, at that! The 30" long stethoscope can be easily configured for (5) different functions, replacing other styles. It comes with (1) large and (1) small diaphragm, (3) different sizes of bell-type chestpieces, (3) sizes of eartips, and instructions for use. The interchangeable parts are in a compact, clear-plastic carrying case that fits into a pocket. Tubing will be assorted neon colors (our choice).

Here’s a fine pair of nylon bristle brushes, just perfect for cleaning test tubes, aquarium filter tubes or your favorite long-necked soda bottle. The smaller brush is approx. 8” long with a 1/2" dia. while the larger is approx.10-1/2” overall with a 1-3/8” dia. The bristle area for both approx. 3-1/2” long.

Agar, it's not just a crossword puzzle answer. It's the medium of choice for growing bacteria, molds, etc., and just what you need if you're shopping for laboratory staples or for your next science-fair project. Melt the medium in a microwave, pour into a Petri dish, and allow to set before applying test material. Do not freeze, and after exposure or melting, store at the temperature on the label. Does approx. 10-12 petri dishes.

Our digital pH meter is ideal for science projects, monitoring your water, keeping your prize-winning tomatoes happy and your aquarium healthy, and more. Has a 1/2" LCD that reads from 0-14 pH with a resolution of 0.2pH. Comes with (3) AG-13 batteries for power, directions for calibration including some 7.01 buffer solution and a screwdriver. Measures approx 5-3/4" long x 1" x 1/2" with a pocket clip and cover for the business end. Made in Romania!
