MAGNETIC STIRRING APPARATUS, A. H . T. Co .Specification . A compact, quiet-running apparatus for vari-able speed stirring action within either closed or open ves-sels. Stirring is accomplished by means of a small mag-netized bar sealed either in Pyrex brand glass or plastic,which is placed in the liquid to be stirred and which is ro-tated by magnetic force applied below the container . Con-sisting of a permanent bar magnet attached to the shaft ofan electric motor and mounted in an aluminum housing withflat top 4 1/4 inches diameter and 41/4 inches high, on castmetal base. Can be used either on the table or on a supportrod, attached by means of a clamp with swivel joint.
Suitable for any stirring operation which involves 1 mlto 1 liter of liquids with viscosities up to that of a 50%glycerol solution . Particularly convenient for use in closedsystems . Any type of vessel of glass, porcelain or non-magnetic metal can be used . A ring-type burner can be usedwhen stirring at elevated temperatures.
9235-R. Stirring Apparatus, Magnetic, A.R.T. Co. Specification, asabove described, with one each magnetized stirring barsA (half-round, plastic coated), and B (round, glasscoated), 1i/ and 13/ inches long, respectively, rheostatwith graduated dial, 8 ft. connecting cord and directionsfor use, but without glassware . For 115 volts, 60 cycles,a.c. only 38.50
