This durable polypropylene separating funnel is a fantastic alternative to the fragile glass lab ware that so often finds itself in pieces on the counter or floor. It has a threaded, leak proof screw cap with a 1.25" diameter and measures 9.5" while upright. The funnel has a 100ml capacity and a 2.25" diameter at its widest point. The polypropylene stopcock is fitted with a self lubricating plug and is fitted to the stem of the funnel. The stem measures 1.75" down from the stopcock and has a .5" diameter.
