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.

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.

Stethos is Greek for chest. Indeed you can scope your stethos with this stethoscope, or your friend's or your dog's. But it works equally well for picking up any sound being transmitted through a solid medium. Listen to the air flowing through the heating ducts, the water in the pipes, the sounds of machinery, the termites munching on the floor joists!! The color does vary so we will select from what's currently available. We've had blue, teal, red, black, burgundy, green and purple, but there may be other colors yet to be seen! A great discovery device whether for biology or other pursuits. Not of professional quality, but not just a toy.

Our magnetic mixer is made for use in a laboratory, but could also be handy if you like your martinis stirred, not shaken, and your arm is tired after a long day in the lab. The unit is 4-3/4" square x 1-7/8" thick (you top it with the appropriate beaker), and stir speed is adjustable from 100 to 1000 rpm. Capacity is 1 liter and the stir bar is a 1" x 5/16" dia Alnico magnet covered with a molded Teflon™ coating for ease of cleaning, and with a center pivot ring for lower friction and better mixing. Now's a good time to think about ordering an extra stir bar, too.
