Kontes 570035-0500 Kuderna-Danish Evaporative Concentrator with Graduated Concentrator Tubes and Polyacetal Clamp, 600mm Height

Kontes 570035-0500 Kuderna-Danish Evaporative Concentrator with Graduated Concentrator Tubes and Polyacetal Clamp, 600mm Height - Preparation involves filling the flask to between 40 to 60 percent of capacity. Lower tube is ungraduated. The water level should be maintained just below the lower joint and the apparatus mounted so that the lower rounded surface of the flask is bathed in steam. The charged assembly should be placed over a vigorously boiling water bath. To prevent sample loss initially, the column should be pre-wet with about 1 ml of the solvent used in the concentration. Developed in the laboratories of julius hyman and company for the concentration of trace amounts of sample dissolved in organic solvents. The final sample remains in the lower tube for further analysis. 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.
