THE IMPROVED "ROCHLITZ" AUTOMATIC WATER STILL 



3812 



3812(a) 



It is well known that the absorptive power of distilled water is second to only 

 that of acids. All but the precious metals and block tin are susceptible to its action, 

 and if it comes in contact with tanks, or pipes of other metals, it will be found to con- 

 tain slight quantities of them in solution. In order to render this contamination 

 impossible, the "Rochlitz" Automatic Water Stills are lined throughout with purest 

 block tin. 



3812 STILL, Automatic, Gas operated (Rochlitz improved). Simple in construc- 

 tion. All parts readily accessible for cleaning when desired. Easily oper- 

 ated and guaranteed to give entire satisfaction. This still is the Rochlitz 

 Still greatly improved and enlarged, made of copper and brass throughout, 

 tin lined inside so that the water comes in contact with the tin only. The 

 outside is nickel plated.

 All impurities are thrown down in the boiling process to the apex of the 

 conical bottom at which point is located the drain pipe and valve. By 

 opening this valve at proper intervals, depending upon the character of 

 the water distilled, all impurities are thoroughly flushed out, keeping the 

 boiling chamber clean and wholesome.
