Designed to maintain distilled solvents in an inert atmosphere. Top of main vapor tube is open and an additional vapor tube has been added to decrease risk of pressure buildup. Upper sampling port has a 4mm Teflon stopcock with a 14/20 outer joint for use with CG-3022 septa. Lower drain is centered to allow total drainage of storage head. Double oblique 2mm bore Teflon stopcock on the 250 through 1000mL sizes allows for removal of distilled solvent or return to flask. The 2500mL size has a 4mm double oblique stopcock. Both the uptake tube and top outer joints are 24/40, while the take-off tube is supplied with either a 14/20 or 24/40 inner joint.

**Design suggested by Dr. A.K. Saksena, Schering Plough Research Institute, Kenilworth NJ.
