Item#: 14803
Tag: HPLC Flex Cube

Description

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 Quick-Change valves. For utmost flexibility, choose among Agilent’s broad portfolio of available valve heads suitable up to 1200 bar. The valves can be controlled independently for any demanding valve-switching application.
