Waters 600 Controller Waters 600 Controller

Waters 600 Controller


The Waters 600 The Waters 600 controller automatically controls the eluent gradient, the flow rate, column heating, external events, and sparging. The Waters 600 Controller can be configured as a PowerLine system controller or as a Gradient controller. The PowerLine configuration is the default configuration that includes programming methods, external device control, and an RS-232 interface. For use within Waters 600 HPLC System.


All of our equipment is fully tested to perform at factory specifications before being shipped.

Included with the Waters 600 Controller:

Includes: Power Cord > Operator's Guide > 90 Day Full Parts and Labor Warranty
