Kontes* Kuderna-Danish Evaporative Concentrators with Polyacetal Clamps or Hooks and Springs

The Kuderna-Danish apparatus was developed in the laboratories of Julius Hyman and Company for the concentration of trace amounts of sample dissolved in organic solvents. The column is designed to speed evaporation with reduced hold up. It is very useful in sample preparation before analysis with solvents such as petroleum ether or hexane.
