It looks as though it should be used for administering laudanum! A 30mL, 1-1/4" sq x 3" tall clear glass bottle, it has thick molded sides and a heavy lip: very antique in appearance. It is stoppered with a red(!) rubber stopper which is the squeeze bulb for the glass dropper tube inside. A real eye catcher, but give it a good wash please. It clearly is not sterile.

Eye dropper, tongue dropper, test tube dropper, petri dish dropper, anywhere dropper. Use this 3" glass dropper, with a rubber squeeze bulb to drop small amounts of liquid wherever you think they should go. You will have to measure by counting drops, though, because there are no markings on it. Also, it is called "3" because that is about how long the glass tube is. Overall, it is 4" long.

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.

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. Our each (20) dishes and lids in a sealed, sterile package.

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.

These clear plastic test tubes hold 10ml and measure 101mm (4") long x 16mm (5/8") dia and come with matching #5 corks. You'll receive a handy package of (10) which is enough for a ROY G. BIV optical display which includes the lesser known colors of not-quite-right green, Monday-morning-blue and plaid. Made in USA.

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.

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.

This funnel looks delicate, but it's borosilicate so heat won't hurt it. The tough little glass funnel has a 75mm (approx 3") ID mouth and an 80mm long neck with a 6mm ID fluted outlet. No markings.

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!

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.

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.

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.

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.

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.

Or funnelette? Whatever. It's a polypropylene mini-funnel, for putting a little something through little openings. Measures 2-1/4" long OA, with a 35mm dia mouth and a fluted, 4mm ID neck.
