9.2.3 Gas ballast adaptor blank
This adaptor kit allows the conversion of a standard nXDS pump into an nXDS

R version.
The gas ballast control is replaced with a blank adaptor so that the gas ballast cannot be
accidentally opened. This feature is useful for applications such as rare gas recirculation
or gas recovery. Another advantage is improved leak tightness at this location.
