115 CONCENTRATORS
Evaporative / Kudema-Danish
Linear Solvent Recovery System for KD Evaporative Concentrators This three-position linear solvent recovery system is intended for use with Kuderna Danish evaporative concentrators.
Kuderna-Danish Apparatus 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.

Proper ventilation under a hood is strongly recommended.
Preparation involves filling the flask to between 40 to 60 percent of capacity. To prevent sample loss initially, column should be pre-wet with about 1 mL of the solvent used in the concentration. If solvent is allowed to escape, entire assembly should be set up in a hood. Charged assembly should be placed over a vigorously boiling water bath. Water level should be maintained just below the lower joint and apparatus mounted so that the lower rounded surface of the flask is bathed in steam. Final sample remains in the lower tube for further analysis.
