The Pharmacia Biotech LCC-501 Plus Controller is a powerful, multi-functional control unit for chromatography systems. Its programmable memory allows you to control chromatographic procedures, modify separation parameters, perform multi-dimensional chromatography, evaluate and print-out data from the chromatogram. You can also control auxiliary equipment such as fraction collectors and chart recorders at the same time. Fifty independent methods can be programmed and stored in its battery backed-up memory. Each method may be accessed individually, linked to other methods or called upon as a submethod. In addition, methods or parts of methods may be looped up to 99 times. Programmed settings may be overridden manually at any stage. Together with prepacked columns, pumps, valves, monitors, and fraction collectors, the LCC-501 Plus forms fully automated systems for fast, high-resolution liquid chromatography, such as FPLC System and BioPilot System.
