Evap Concentrator 500ml

Not yet rated

Developed in the laboratories of Julius Hyman and Company for the concentration of trace amounts of sample dissolved in organic solvents. It is very useful in sample preparation before analysis with solvents such as petroleum ether or hexane.

Preparation involves filling the flask to between 40 to 60 percent of capacity. To prevent sample loss initially, the column should be pre-wet with about 1 mL of the solvent used in the concentration. The column is designed to speed evaporation with reduced hold-up.

The charged assembly should be placed over a vigorously boiling water bath. 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 final sample remains in the lower tube for further analysis. Lower tube is ungraduated.

If solvent is allowed to escape, the entire assembly should be set up in a hood. For solvent recovery, a 547300 or 547400 Solvent Recovery Apparatus may be added to this unit. Series 570025 and 570035 have graduated concentrator tubes.
