DURAN Separating Funnel 21013240

DURAN Separating Funnel 21013240

The DURAN Separating Funnel 21013240 is designed for efficient liquid-liquid extraction and phase separation in chemical, analytical, and research laboratories. Its conical shape helps sharply delineate immiscible layers, enabling clean separation. The funnel includes a solid glass key stopcock and a ground glass stopper, giving precise flow control and chemical compatibility without use of PTFE or other materials that may leach.

Manufactured from borosilicate glass 3.3 (DURAN), the funnel provides excellent chemical resistance, thermal stability, and durability under repeated use. The ground glass joints and solid key ensure tight sealing, minimizing leakage or contamination during extraction steps.

This model meets DIN/ISO standards for glassware in lab separations, and is suitable for routine solvent separations, washing operations, and clean phase transfers.
