The Agilent 1290 Infinity Flexible Cube is an auxiliary module for the 1290 Infinity Autosampler with a built-in pump to facilitate enhanced flushing capabilities and to reduce carry-over. With access to three solvents, critical sections of flow path can be flushed at high flow rates. Automated back-flushing of the injection needle-seat achieves the absolute lowest sample carryover for LC and LC/MS applications. In addition, the Flexible Cube hosts up to two Agilent InfinityLab Quick Change valves. For utmost flexibility, choose among Agilent’s broad portfolio of available valve heads suitable up to 1300 bar. The valves can be controlled independently for any demanding valve-switching application.
