DURAN Separating Funnel 21013241 100 mL
The DURAN Separating Funnel 21013241 100 mL is engineered for micro-scale liquid-liquid extractions and solvent separations requiring precision and chemical resistance. Its conical shape promotes a sharp interface between immiscible liquid phases, thereby reducing cross-contamination.
Constructed of DURAN borosilicate glass 3.3, the funnel affords excellent chemical durability and resistance to thermal variation. The PTFE (Teflon) key stopcock ensures smooth, grease-free operation and minimal friction, while the ground glass stopper provides a tight seal during mixing or shaking. PTFE keys are known for requiring no lubrication and offering broad chemical compatibility.
This 100 mL model is well suited for small-volume experiments in research, quality control, and academic settings, supporting repeatability, clarity, and durability in laboratory separations.
