DURAN Separating Funnel 21013361 250 mL

DURAN Separating Funnel 21013361 250 mL

The DURAN Separating Funnel 21013361 250 mL is crafted for efficient liquid–liquid extraction and phase separation. Its conical shape promotes sharp interface formation between immiscible liquids, enabling clean separation.

Made from borosilicate glass 3.3, it resists chemical attack and thermal stress. The PTFE key stopcock ensures smooth, grease-free operation and reliable flow control, while the ground glass stopper forms a tight seal to prevent vapor escape or contamination.

Ideal for analytical, synthetic, and purification workflows, this 250 mL funnel supports reproducible performance in demanding laboratory applications.
