 |
Ideal for use in HPLC applications |
|
Pulse dampener significantly reduces pulsation with low dead volume. |
| Preparative digital pump provides high flow rates and high pressure capabilities with consistent performance. Dual ball and seat check valves in each head reduce pulsation. | |
|
Microprocessor controls motor drive circuits, interfaces with the chemical-resistant keypad and digital LED display, receives signals to refill based on flow rate, and provides RS-232 communication. Pressure control feature provides real-time pressure monitoring with upper and lower pressure limits. Other features include prime/purge valves for easy solvent change and priming capabilities, auto-flush piston wash, run/stop inputs, and dual-voltage capabilities. Includes a 6-ft power cord with plug. |
