Separatory funnels are used for liquid-liquid extractions, separating a mixture's components into two liquid phases of different densities. The higher density liquid sinks to the bottom and can then be drained from a valve, leaving the less dense liquid in the funnel. Separatory funnels feature a stopcock at the bottom that can be opened or closed to drain liquid, as well as a stopper at the top that can be opened to release excess vapor pressure. The funnels are typically constructed from borosilicate glass, which is stronger than regular glass and resistant to thermal shock.
Features a 24/40 top joint and includes a stopper. Bottom PTFE drain valve does not require grease and the bore is 2.8mm for 250, 500, and 1000mL, and is 3.8mm for the 2000mL separatory funnels. Angle cut drip tip for precise dispensing of the drained materials.
