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.

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.

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.

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.

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.

These blue glass dropper bottles are the color of the cold cream bottles that everybody's mother used when everybody's mother used cold cream. Measure 3-1/8" tall x 1-15/16" dia and hold (1) oz. Plastic safety dropper cap is 2-3/8" tall and marked at 0.4 and 0.8ml.

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.

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.

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.

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!
