Closed Stem Funnels are designed for delicate applications like Chromatography, in which fluid from the funnel should minimally impact the contents of the container.
These unique closed-end funnels have small holes around the base of the stem, which is otherwise completely blocked, and liquid flows out several places at once and trickles down the container side walls. (Click image to left for enlarged view.)
Delicate application closed stem funnels are virtually unbreakable and made of chemically resistant high density polyethylene (HDPE). They are spark proof, rust proof, dent proof and boil proof. Available in individual sizes or as a complete set of 5 funnels (60mL, 120mL, 240mL, 960mL and 960mL with a wide neck opening.
