120 mL HDPE Chromatography Funnel is a small solvent addition funnel designed for controlled delivery of mobile phase during column chromatography. The high-density polyethylene (HDPE) construction provides strong resistance to common organic solvents and eliminates breakage concerns associated with glass. Perforated side openings and a closed stem guide solvent down the column wall to help maintain uniform packing and minimize disturbance of silica beds during separations.
