DWK Life Sciences Separating Funnels, 250 mL DURAN, Conical Form

A standard laboratory extraction funnel, the DWK Life Sciences DURAN® Separating Funnel, Conical, 250 mL, PTFE Stopcock, NS 29/32 lets chemists separate and recover solvent layers cleanly thanks to its conical, pear-shaped body and metered outlet. Its PTFE stopcock resists aggressive solvents and needs no lubrication, reducing the risk of sample contamination. The body is DURAN® borosilicate glass 3.3, giving high resistance to chemical attack and repeated cleaning.
