Answer:Up to five connected chromatography columns.
Answer:Yes. The valve has integrated bypass and reverse-flow functionality.
Answer:V9-C is a five-column valve, while V9-Cs is a one-column configuration.
Column Valve Kit V9-C enables automated selection among as many as five connected chromatography columns on an ÄKTA pure 25 system. It supports column scouting, method development, and programmed switching between separation media without routine manual reconnection of every column. The integrated column bypass allows the flow path to avoid a packed column during selected washing operations, while reverse-flow functionality can assist appropriately designed cleaning or elution steps. Pressure measurements before and after the connected column can support monitoring of pressure drop across the packed bed. This kit is the five-position V9-C variant; it differs from the single-position V9-Cs and the separate second five-position V9-C2. The valve is a system module, not a packed chromatography column.
