Vigreux Distillation Columns Joint Size:19/22 Flash column chromatography uses pressurized

Flash column chromatography uses pressurized gas to drive solvent through the column

This Jacketed reflux condenser has one threaded joint at the top and one inner joint at the bottom

Positioned between the rotary evaporator vapor tube and flask

Available with a 2 mm bore (11/25 plug size) or 4 mm bore (15

Designed to meet ASTM E1406

Vigreux Distillation Columns Joint Size:19/22 Flash column chromatography uses pressurizedThe Vigreux style column features internal indentations running the full length of the column, increasing surface area to improve vapor liquid contact for efficient fractional distillation. Features the same size top outer and lower inner standard taper joints. The effective height is measured from the highest to the lowest indentation in the distilling column. Made of borosilicate glass for excellent chemical durability and mechanical strength.
