Laboratories have enjoyed the convenience of magnetic stirring for many years; in fact, magnetic stirring has been the only simple method to use with narrow-necked vessels or completely closed systems. However, heating liquids while stirring magnetically was difficult . . . if not impossible . . . until Arthur S. LaPine & Company introduced the LANCO Combined H o t Plate-Magnetic Stirrer. T h e base of the apparatus illustrated above is a light casting and houses the controls for heating and stirring and the stirrer motor. T h e hot plate assembly plugs into the top of the base and is easily removable. A stainless steel support rod threads into the base. With each LANCO unit is supplied a glass-enclosed stirring magnet. Rheostat control of the motor enables dialing in the most effective speed for stirring a particular liquid. An input controller obtains infinitely variable heating from 0 to 400 watts. Both rheostat and input controller have "off" positions, so that stirring and heating are independent of each other and can be used separately or together. CATALOG N O .
