KOBE CONDENSER 



IMPROVED BY EEMER AND AMEND 



Has three sets of walls. The outer wall receives the water 

 for cooling through the upper side tubes. Thence the water 

 passes through the coiled inner tube and out by the lower side 

 tube. The distillate enters the adapter at the top, passes 

 through the expanded middle tube and out by the tube at the 

 bottom, while in the expanded middle tube the distillate is 

 cooled 



a. By the expansion of the middle tube. 



b. By the jacket of cold water around it. 



c. By the cold tube coiled inside of it. 



A Kobe Condenser of this type with body 6" long is as effi- 

 cient as"a regular Liebig condenser, with body 35 or 40" long. 

 Due to the expanded tube it may be used either as a regular 

 condenser or as a reflux, being in this respect like an Allihn, 

 but four or five times as efficient. It is especially recom- 

 mended for liquids of low boiling point. On liquids of high boiling point its 

 relative efficiency is somewhat decreased, though it is still much more effi- 

 cient than other forms. 



Price of regular size with 6" body $5.00 Prompt Shipment
