Wayte Laboratory Centrifuge 



This centrifuge has been designed and built to supply an ever 

 increasing demand for a laboratory apparatus that will quickly 

 and efficiently separate crystals and precipitates from their 

 mother liquids by centrifugal force. The centrifugal basket 

 revolves at a speed of up to 10,000 revolutions per minute, 

 forcing the liquid through a fine mesh screen into the outer 

 curb from whence it is drained into a graduate or other re- 

 ceptacle. 



The machine's outer casing is made of the finest cast 

 iron. All of the gears are cut and are enclosed at the base, 

 protected from moisture and are silent and powerful in their 

 action. The perforated basket is made of solid bronze and 

 will hold about i lb. of material. The diameter of the basket 

 is about 43^" and revolves at the speed of 3,000 revolutions 

 per minute to 20 turns of the handle, and by increasing 

 the speed of the handle the machine may be brought up to 

 10,000 revolutions per minute.
