So Pat went a little crackers and bought approximately 897 gazillion #00 rubber stoppers, enough to stop up every small test tube in every high school science lab from here to Osaka. You'll get a bag o' (1,000) of them. We know you'll find a crafty use: tiny bowling games, non-conductive earrings and necklaces, little bumper car bumpers, traffic cones for cockroaches, stubby guitar picks.... In black rubber conic sections, 1" long x 10mm (0.39") at the bottom x 14mm (0.55") at the top, or vice versa.

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.

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.

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.

You’ll get (10) pieces of clear acrylic medical grade tubing for your water fountains, Halloween displays or other hobby projects. Each measures 32” long x 5/32” OD x 1/8” ID. Made right here in the US of A.

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!

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.

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).

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.

Our fashion buyers are just back from the shows in Milan with these brand new, nice quality, 80% poly/20% cotton lab coats. These are Euro-sizes, which generally (and generously) match chest circumference. The 42 has 34-1/2" sleeves, and the 48 has 36". All are about 39" long, which means fingertip length or mid-thigh, depending on how long you are. Think men's small and XL. They're all five-button, with one breast pocket and two large side pockets and have no name or embroidery added. Notched lapels, no vent-just what all the best-dressed technicians are wearing this season.

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.

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.

So we're pricing these borosilicate boiling flasks to move quickly. We've got (3) sizes, all with slightly flattened bottoms, each with a single, discreet, capacity mark in white. While the actual physical size can vary slightly, the volume remains the same. The 1000ml flask is 9-5/8" tall OA x 5-5/8" dia with a 1-5/16" ID mouth, and a lip. Takes a #7 rubber stopper. The 500ml flask is 6-7/8" tall OA x 4-1/8" dia with a 1-3/16" ID mouth, and a lip. Takes a #6-1/2 rubber stopper, but a #7 will work. The 250ml flask is 6-1/8" tall OA x 3-3/8" dia with a 1-1/32" ID mouth, and a lip. Takes a #5-1/2 rubber stopper, but a #6 will do the job.

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.

Clamps. Whatever. These measure approx 5" long x 1-1/2"' at their widest. They open to about 2", though, so they'll not only grab test tubes, they'll pluck cubes from an ice bucket. Or carry a few stems of asparagus. And you do get a pair, so you could always have a tong war.

Up close and personal. From My First Lab™, these prepared microscope slides are Biology 101 in a box. Fungus slides (“Fun Guys”) have bread mold, penicillum, lichens, mushroom and yeast samples. The guts group has human stomach, heart and blood, plus brain and kidney cells from a small mammal. For ages nine and up.

Jumbo sized cork for all your corking needs. Bottles or crafts its the perfect size. 1-1/4" top x 1-1/16" bottom and 15/16" tall. Cork away!
