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.

Microscope glassware for examination of blood, pond water, mold, and other minutiae. All of the microscope slides are optically clear glass 26mm x 76mm (about 1" x 3"), between 1mm and 1.2mm thick. The well slides, of course, have a concave well to hold a drop of liquid. Our each is a package of (12) well slides, or a box of (72) standard slides with ground or beveled edges. Cover glasses are the smaller and very thin pieces of glass used as the top of the glass slide sandwich. They are often used temporarily by simply dropping them onto a drop of liquid to flatten and spread it and to minimize evaporation. More confident microscopists will cement them in place to permanently preserve a specimen. Our each is a package of (100) cover glasses 18 mm square, #1 thickness (0.13mm to 0.17mm). If you need one, you need both.

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.

And a pestle to match. This 900ml, large-capacity mortar and pestle set is made for the lab but would also be proud to serve in your kitchen. (Call it the Guac Pot.) Mortar measures 6-1/4” across x 3-3/4” tall with a 7-1/2” long pestle with a 1-7/8” dia head, big enough to pestle anything into submission.

Getting tired of buying them and trimming them and losing them? Get rid of wicks altogether with this nifty little alcohol burner with a copper capillary tube in place of a cotton wick. Burns 90ml of denatured alcohol and comes with a heat shield (packed inside the reservoir) and a burner cap. Don't forget to remove the little rubber plug - it's there to cover the holes in the copper tube when not in use. And this is lab equipment, so resist the temptation to use it under a chafing dish; initially, it flares up a tad more than is good for Swedish meatballs.

This excellent 500ml capacity essential oil distillation set comes with an 18" lab stand, 2-1/2" ID support ring, single buret clamp and borosilicate glassware with a 500ml round-bottom (just like you!) and 24/40 ground glass joints. Also includes a boiling flask, 300mm Graham condenser, 500ml Erlenmeyer flask and a 10" adapter arm. Make your own perfume or something more potent--we don't judge. You supply some 3/8" ID tubing for the condenser. Check out our other lab distillation kit and small glass bottles, perfect for storing your essentials.

Polypropylene beakers times five. The nesting set includes a 50ml (marked in 5ml increments) beaker 2-1/8" tall x 2", a 100ml (5ml incr) 2-3/8" x 2-3/8", a 250ml (10ml incr) 3-7/8" x 3-1/4", a 500ml (10ml incr) 4-5/8"x 4", and a 1000ml (25ml incr) 5-3/4" x 4-7/8", all with lips and pouring spouts.

Hard polypropylene beakers, milky white with a fine pouring spout. No good for flames, but great for low-temp lab applications. Also useful in the kitchen, the garage, or (the big one especially) as a plant watering can.

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.

Grow your own bacteria with this lab kit from EduSci. You get (3) sealed sterile Petri dishes plus a 1/8-oz bag of agar and instructions for use. Bonus: they teach you that agar is pronounced like jogger without the j.

Two sizes of Bomex separatory funnels with ground glass stoppers and petcocks. The 100ml funnel is 9-1/2" long overall. The 500ml is 14-1/2" overall. An excellent price for basic lab glassware.

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.

Rejoice, we have finally found a source of reasonably priced borosilicate lab glassware. This is the kind of glass in the trade marked Pyrex(tm) and Kimax(tm) labware. The stuff you can put right over the flame of the Bunsen burner, or directly onto the hot plate. This stuff is imported from China, and is considered student grade, which is good enough for anything but the most exotic applications. We have beakers, test tubes, graduated cylinders and flasks. Compare the prices below and you will see that they are around half the U.S. equivalent. Call us for larger quantity prices.

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. You add some 1/4" ID tubing for the Liebig ports. Includes good directions for distilling ethanol and acetic acid.

Made for extended chemistry experiments, our really long borosilicate test tube is 18mm (23/32") outside dia. x an incredible 32" long, with no lip. (And we don't want any lip anyway.) No chemistry experiment? Feed strings of small holiday lights into a handful of them and create a dazzling light fixture. Or play the get-the-worm game with really extraordinary tequila shots!

You could melt metals in these ceramic crucibles, or you could just line them up and look at them, they're such pure design objects. Not bad as condiment pots, either. You pick the 50ml, measuring 1-3/4" tall x 1-7/8" ID at the top, or the 100ml, 2-1/4" tall x 2-3/8" ID at the top. White, with unglazed bottoms and lips, in an inverted bell shape with a hole for a wire.

Vials is a much nicer name than little skinny bottles, doncha think? These amber glass vials are 5/8" dia with a 5/16" ID and come with a gasketed black plastic screw cap. You pick the short one, at 1-1/2" tall and holding 2ml (0.135 oz) or the tall boy, 2-1/2" tall, holding 8ml (0.27 oz).

The Graduate devotee knows the importance of plastic. To fill the need we offer these fine cylinders of the hard milky white polypropylene persuasion, to help you measure out your chemicals. With a large bases for stability and spouts for pouring, they are just like their glass cousins, except these are cheaper and not heat-resistant (each is marked 20° C ?!). The graduation increments and total volume are shown as increment/total in milliliters.
