Pyrex* Kuderna-Danish Jacketed Concentrator Tube

The innovative Pyrex* jacketed Kuderna-Danish concentrator tube circulates hot water through the jacket to boil the solvent during extraction/concentration. The bottom portion of the tube is never heated, so samples won't boil dry. The concentration automatically stops when the solvent sinks below the jacket. Lab technician time is saved by eliminating the need to watch evaporations closely to avoid boiling dry. With serrated tubulations or screw thread connections for fast set up and tear down.
