You don't have to keep paint in these, but they're exactly like the little glass jars that tempera paints used to come in before everything came in plastic. Measure 2-1/2" tall x 2" dia in clear glass with white metal gasketed screw caps and hold (2) oz.
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.
A great find: sterile plastic petri dishes, 100mm 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.
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 or lab concoctions as you prefer.
You get a mortar and pestle as a single order.
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.
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.
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. And let's remember that this is for laboratory distilling. Don't try this at home.
Blue plastic test tube rack, about 8" long x 2-1/2" wide x 3-1/4" tall OA. It has a plate with (6) holes for full test tubes, the end two being 1-1/16" / 27mm dia the others 3/4" / 19mm dia. In front of this are (6) pegs to hold clean inverted test tubes. It of course can be used to hold tools, drying pasta or other, non-lab objects.
