DURAN Separating Funnel 242941704 50 mL

The DURAN Separating Funnel 242941704 (50 mL) is engineered for liquid–liquid extraction and separation of immiscible phases in analytical and synthetic laboratories. Its conical shape promotes sharp phase delineation for precise separation.

It features a solid glass key stopcock, offering reliable and grease-free control of fluid discharge, paired with a plastic stopper that seals the top to prevent vapor or liquid escape during mixing. The funnel does not include a graduated scale. According to Fisher Scientific, this model includes the ground glass stopcock + plastic retaining device + plastic stopper.

Manufactured from borosilicate glass 3.3, it provides excellent resistance to thermal shock and chemical attack. The joint and materials are autoclavable, enabling safe reuse in sterilizable lab environments. Fisher’s catalog lists this under “separating funnel, conical, with glass key, 50 mL.”

This funnel is optimal for small-scale solvent extractions, washing operations, and phase transfers in research, quality control, and academic settings.
