Liquid-Liquid Continuous Extractor with PTFE Stopcock

This liquid-liquid continuous extractor is designed for EPA priority pollutant samples where the extracting solvent is heavier than water. It is sized for samples of 1 liter plus approximately 200 mL of extracting solvent and features a 2 mm PTFE stopcock on the sidearm to stop the flow after extraction is complete. The extractor has a 45/50 top outer joint and a 24/40 inner joint on the uptake tube.

A complete setup would include a CG-1506-23 1,000 mL round bottom flask and CG-1368-05 medium condenser, each sold separately.

A similar item without the PTFE stopcock on the return tube is available as item # CG-1360.
