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.

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.

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.
