 Centrifuge 



No. 1420 



Our general laboratory centrifuge 

 is of very heavy construction. It 

 is completely enveloped in a pro- 

 tective dome that is an integral 

 part of the centrifuge and of the 

 same construction as the balance 

 of the machine. 



The machine is designed to pemiit 

 the use of a large variety of centri- 

 fuge heads with all the various types 



of tubes usually used by such an apparatus. Its maximum capacity is eight 



50 cc. tubes or eight Babcock milk bottles. 



It is operated at five different speeds that are controlled by a rheostat that 

 is a direct part of the machine and enclosed in the base. 



No special wiring is necessary as the machine may be attached to any ordi- 

 nary lighting circuit, either direct or alternating current. 



The centrifuge, using a two 15 cc. tube head on direct current attains a speed 

 of 4300 (on alternating current 4100) revolutions per minute, a higher speed 

 than that developed by any other type of centrifuge of its kind now on the 

 market. 



The high 'power of the motor and its smooth running qualities, backed as it 

 is by an absolute guarantee, make it the most desirable centrifuge made.
