The Kuderna-Danish apparatus was developed 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.

  • Graduated concentrator tube
  • Tube Capacity 10mL
  • Tube Subdivisions (mL): 0-1mL in 0.1mL units, 2-10mL in 1mL units
  • For solvent recovery, a 547300 or 547400 Solvent Recovery Apparatus may be added to this unit
  • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements

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 1mL 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.

†Polyacetal clamps are recommended for safety.
