Co-developed and marketed by Süd-Chemie and Mitsubishi Gas Chemical, PharmaKeep® is an innovative and unique line of polymer-based oxygen absorbers that are "humidity neutral." Unlike traditional iron oxide oxygen scavengers, PharmaKeep® requires no moisture to react.  

Available as canisters and packets, PharmaKeep oxygen absorbers protect pharmaceutical and diagnostic products from oxygen degradation and oxidative reactions, thus extending the shelf life.  Because they do not require humidity to function, PharmaKeep can be used in conjunction with desiccants.
