NEW! COVID-19 Products
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 similar item without the PTFE stopcock on the return tube is available as item # CG-1360.
