EW-74930-20 High-Pressure Gradient Piston Pump
Preparative Digital High-Pressure Gradient Piston Pump
EW-74930-20
- Deliver precise volumes at pressures up to 6000 psi
- 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.
What's Included:
6-ft power cord with plug
