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.
