HOW TO CURE MIXER-ITIS Fed up with electric mixer repair bills? Give those worn-out mixers the boot and treat your lab to a new economy: the LIGHTNIN Mixer, Model L. It weighs just eight pounds. But i t ' s built to mix . . . and mix . . . and mix— for weeks at a time—without attention. You can use it for years without maintenance or adjustment. Hundreds of users do. The 1/30-hp totally enclosed fancooled motor spins the shaft at a quiet, steady 1600 rpm; is safe with flammables. You can vary the mixing action by replacing the 2-inch propeller with different types. Propeller and shaft come in 3 1 6 stainless steel or Monel. Your choice, too, of bronze tank clamp or ring-stand clamp. Order from your supply house, or write us. Specify LIGHTNIN Model L Mixer: For H O v 60cy l p h
