Waters LC Module I

This compact, fully integrated system is in excellent condition and tested at GenTech. Includes multisolvent delivery, automated sample injection, and high sensitivity UV/Vis detection for the high volume, high throughput laboratory. Fully automated and validated, the LC Module I is ideal for the regulatory-compliant laboratory that needs efficient and effective analyses. Preventive maintenance features, such as pump and seal wash, lamp save and self-diagnostic procedures, ensure the long-term integrity of the unit. The system features fast setup, unattended operation with automated start-up and shut-down routines, including priming and flushing and ability to program up to 96 vials of varying injection volumes and injections per vial. It incorporates a 715 Autosampler, 600 Pump & 486 Detector in one unit. Includes SIX (6) MONTH WARRANTY.
