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.

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.

So you don't have a gas jet in the garage? You don't think Margie and Ted are old enough to handle the high temperatures of a Bunsen burner? Our alcohol lamp is the answer. It burns alcohol (available at the hardware store), and is hot enough to boil water, to soften glass tubing for bending, and to generate the chemical reactions generally called for in science projects. The lamp is shaped like a long-necked ink well, 3-1/2" tall x 3" dia at its widest point and comes with a wick assembly and a handy little glass lid/extinguisher.

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.

For students or professionals, this Celestron® Deluxe Handheld Digital Microscope that captures still images and videos is a terrific computer accessory. Plug the USB 2.0 cable into your computer's port and take advantage of the built-in, upgraded 2MP CMOS sensor, 10X to 200X magnification, and 8-LED illumination. It features a 1 sec. to 1/1000 sec shutter speed, 1920x1080, 1280x720 and 640x480 resolutions, max 30fps videos, 10mm to 150mm manual focus and a 2 element glass lens with IR Cut and EFL 158mm. The 4-oz, 4-1/4" x 1-1/4" dia scope may be handheld, or slipped into its metal stand for steadier viewing. Includes CD-ROM software with measurement function and note-taking and a calibration tool. Works with Windows 7/8/10 and MAC OSX 10.12 and up. Very cool.

This blue plastic test-tube rack measures approx 8" long x 2-1/2" wide x 3-1/4" tall with (6) holes for full tubes, the end ones at 1-1/16" / 27mm dia and the others at 3/4" / 19mm. In front of these are (6) pegs for clean inverted tubes.

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.

These 6” steel dissection probes have knurled handles above 1-1/4” long x very sharp 1/16” points. Ignore the “Oil Pick” name on the package. We don’t know what it means either, other than that it translates to “surplus bargain".

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.

Our each is box of (100) round filter papers, 12.5cm (approx 4.92") dia x 0.15mm thick (#1 size). No lab? Think craft supplies, throw-away coasters, or little caps to keep the gnats out of your pina colada.

Fearful of language barriers, some folks get anxious when they travel internationally. Not this fine red-alcohol glass thermometer. Whether its travels take it to Britannia or Madagascar, Appalachia or Moscow, it's always ready to tell the temperature in the local tongue. Working stateside? No problem: it reads 0° to 230° F, in 2° increments. On a junket across the pond? Again, the Passport Therm shines, reading -20° to 110° C in 1° increments. It's 11-3/4" long, 3/16" dia, and travels in a nothing-special-but-still-handy plastic case.

A great find: sterile plastic petri dishes, 90mm dia x 15mm deep, with a loose fitting lid. Great for growing cultures for your science fair experiments, as individual pancake storage cases or for mixing paint. Our each is (25) dishes and lids in a sealed, sterile package.

We have obtained a large number of real natural corks ranging across the popular sizes used in science labs to seal vessels (drill your own holes for glass tubing, etc), use as floats and as a great craft item. Or just use them to seal bottles that don't have closures or cry out for a decorative seal.

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.

Like the ubiquitous oxygen tubing found in medical settings everywhere, we have this clear acrylic tubing available in 23-1/2" long pieces. Tubes measure 9/32" OD x 5/32" ID. Great for fountains, science fair projects, Halloween costumes, unique holiday decorations and modern sculpture.

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, fresh herbs or lab concoctions as you prefer. You get a mortar and pestle as a single order.

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.

But science teachers can't work without them. Experiment with this good-quality manual vacuum pump made of durable polychloroethylene plastic. Works with a pistol-grip action and pulls up to 2" Hg. Includes a 17" length of clear vinyl, 1/4" ID tubing, and a release valve.
