ChemoPlus™ IVA seals for I.V. bags are sterile seals that protect point of entry of IV admixtures from contamination and accidental double dosing. They have a dual warning system in which seals self-destruct upon attempted removal, and needle punctures are highly visible in laminted foil. Having ChemoPlus™ IVA seals on bags instantly alerts staff that a durg has been added. Latex Free.
