Wet chemical analysis by definition includes handling liquid reagents. Exposure to chemicals during reagent exchange is a potential hazard to the health of laboratory workers, especially when removing aspiration tubes from bottles with toxic content.  

Metrohm present the OMNIS Liquid Adapter, a new technology that puts an end to this risk altogether by handling reagents in a closed system during reagent exchange. 

The patented OMNIS Liquid Adapter is simply snapped onto a corresponding bottle cap that is part of the reagent bottle. As soon as this liquid adapter is connected to the bottle cap, reagent from the bottle can be aspirated by the system and the analysis can be started.
