Product Description
Large-volume extractions are slowed down when draining liquid swirls and pulls the upper layer back into the lower one. This non-vortexing funnel prevents that remixing, so phases drain cleanly and you lose less time waiting for layers to settle again.
This listing is for Kimble catalog number 636200-4000: KONTES Separatory Funnel, 4000 mL. An internal baffle plate diverts the draining liquid and stops a vortex from forming at the outlet. The funnel is made from 33 expansion low-extractable borosilicate glass meeting USP Type I and ASTM E438 Type I, Class A, and it has a PTFE stopcock and a 29/42 standard taper center joint. This model holds 4000 mL. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
