New Agilent G4227A module. Flex Cube 1290 Infinity. The Agilent 1290 Infinity Flex Cube is an auxiliary module for the 1290 Infinity autosampler with an integrated pump to provide improved flushing capabilities and reduce carryover. With access to three solvents, critical portions of the flow path can be flushed at high flow rates. Automatic backwashing of the injection needle seat assembly achieves the absolute lowest sample transfer for LC and LC/MS applications. In addition, the Flex Cube houses up to two Agilent Quick-Change valves. For maximum flexibility, choose from Agilent's wide portfolio of available valve heads, suitable up to 1200 bar. The valves can be controlled independently for any demanding valve switching application. Specifications Injection area. 1 - 20 µL. 1 - 40 µL. 1 - 100 µL. in 0. 1 µL increments.
