DURAN Separating Funnel 21013541 1000 mL
The DURAN Separating Funnel 21013541 (1000 mL) is a precision laboratory instrument for liquid–liquid extraction, designed to separate immiscible liquid phases with clarity and control.
Its conical shape allows sharp boundary formation between organic and aqueous layers, ensuring accurate collection without cross-contamination.
Crafted from DURAN borosilicate glass 3.3, it offers high chemical resistance, excellent thermal stability, and long-term durability. The PTFE (Teflon) key stopcock provides effortless, smooth flow control with leak-free performance, while the ground glass stopper guarantees a secure seal during shaking or mixing.
Fully autoclavable and compliant with DIN/ISO standards, this funnel is ideal for analytical, organic, pharmaceutical, and academic laboratories that require precision and chemical integrity.
