The Waters 1525 Binary HPLC Pump is integrated, high-pressure, binary HPLC pump that feature on-board pulse dampening and efficient mixing. Their pulse-free solvent flow, from analytical to semi-preparative flow rates, upto 30 ml/min for each pump in semi prep function, makes them ideal for use with highly sensitive detectors.
The Waters 1525 Binary HPLC Pump is designed for use with 2 to 4.6 mm I.D. columns in routine LC and LC/MS applications. They have a programmable flow-rate range of 0.00 to 10.00 mL/min in 0.01 mL increments.
Optional features:
- Extended Flow (EF) heads for extended flow rate range up to 22.50 mL/min for use with 10 to 19 mm I.D. columns
- 1500 Series Column Heater with a temperature range of 20 to 60 °C to maintain accurate, consistent column temperature
- Integral vacuum degasser to remove dissolved gases from the mobile phase, improving performance and reliability
- Automated seal wash helps extend the primary seal life for reliable operation
- FlexInject manual dual injector module for both analytical and semi-preparative injections
