DURAN Separating Funnel 21013540
The DURAN 21013540 Separating Funnel (1000 mL) is designed for efficient liquid-liquid extraction and phase separation in laboratory environments. Its conical shape promotes clean and complete separation between immiscible liquids such as aqueous and organic phases.
Manufactured from high-grade DURAN borosilicate glass 3.3, this funnel provides outstanding resistance to chemicals and thermal stress, maintaining reliability under frequent use. The solid glass key stopcock enables fine control over liquid discharge without the need for grease or PTFE components, while the ground glass stopper ensures an airtight seal for mixing or shaking without leakage.
Fully autoclavable and built to DIN/ISO standards, this funnel supports safe, repeatable operation in chemical, pharmaceutical, academic, and analytical laboratories.
