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.

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.  

Great for the lab or for those hobby projects that require a little measuring. Our rubber-bulb syringe holds up to 50cc and is marked in 1cc increments. Has a 3/16" ID tip and measures 8-1/4" long with a 2-3/8" dia. bulb. Get creative and think outside the box. You'll get a package of (3).

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.

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.

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.

Almost big enough to pick up mortals: 10" long, 15/16" wide, with a mouth that rests open at 1-3/16". Stainless steel, non-magnetic tip, with a smooth, ungrooved tip that's .046" wide. Good for giant splinters, crafts, jewelry, electronics, or sushi.

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 400mL one has graduations in 50mL increments and the larger 1000mL one in 100mL increments with numeric markings every 100mL or 200mL accordingly; both with more room before you have to worry about spilling. Not intended for serious lab use as the volumes are approximates. Remember to ask for 236.5ml of coffee the next time you visit your favorite diner.

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.

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 8-1/2” long with a 1/2" dia. while the larger is 10-1/2” overall with a 1-3/8” dia. The bristle area for both is approx. 3-1/2” long.

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.

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!

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.

Each non-sterile transfer pipet measures 6-1/8" long, with a 1mm mouth, a 3/16" dia neck, and a 1/2" dia bulb. It holds 3.5ml, including the bulb, and is graduated up to 1ml in .25ml increments on the stem. Made for a laboratory, of course, but equally useful in the kitchen, for portioning out that aceto balsamico tradizionale di Modena you paid $80 an ounce for.

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.

On a slightly convex aluminum plate, with small mounting holes top and bottom. Our glass alcohol 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 element. Made for the laboratory, but nicely readable and able to hang on your wall without looking like part of a weather station.

Distillation made heuristic. Nothing explains a process like a little hands-on experience, and this laboratory distillation kit is for showing instead of telling. Includes a 300mm Liebig condenser, Kjeldahl distilling column with 50mm dia bulb and rubber stoppers, 500ml Bomex boiling flask with 8" iron tripod, 2-foot lab stand/base with a single burette clamp, 500ml graduated Erlenmeyer flask and a 6" square of ceramic-coated wire gauze.
