B&J NOWPAK® and NOWPAK ® II Containers
A recyclable packaging alternative to glass bottles, the B&J NOWPAK® container maintains solvent purity, increases lab safety and maximizes efficiency when using larger solvent volumes. High purity solvent is contained in an inert, specially cleaned liner inside a rigid high density polyethylene (NOWPAK®) or 304 stainless steel (NOWPAK® II) overpack.
