DWK Life Sciences DURAN Separating Funnel, Conical, 1000 mL

Where solvent extraction calls for a larger-volume funnel, the DWK Life Sciences DURAN® Separating Funnel, Conical, 1000 mL, PTFE Stopcock, NS 29/32 pairs a conical, pear-shaped body with controlled bottom delivery for larger-batch preparative work. 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.
