Agilent 1290 Infinity Flexible Cube 

The Agilent 1290 Infinity Flexible Cube is an auxiliary module for the 1290 Infinity Autosampler with a built-in pump and valves to facilitate enhanced flushing capabilities. With access to three solvents you can flush critical parts of the flow path at high flow rates. Automated back-flushing of the injection needle-seat achieves absolute lowest sample carryover, eliminating resource and time-consuming carryover reduction procedures during LC and LC/MS assay development. Up to two Agilent Quick-Change valves with ultrahigh pressure valve heads can be controlled independently for demanding valve-switching applications (available shortly).
