CENTRIFUGE, Victor No. 4, for heavy work and wide range of speed. The motor, arranged for 

 both 110 volts A. C. and D. C., is entirely shut off from the centrifuge chamber, eliminating any 

 danger of ignition of combustible vapors from sparking. The protective dome is cast as an 

 integral part of the motor housing, and is provided with a heavy hinged lid. A rheostat in the 

 base permits five different ranges of speed. A variety of multiple tube heads may be used and 

 greater speed can be obtained than with the No. 2 or No. 3. Complete with four-tube head 

 with attached trunnion rings, four 15 cc round bottomed bronze shields with rubber cushions, 

 and attachment cord and plug, without glassware.
