The 15251525 with EF heads are integrated, high-pressure, binary HPLC pumps that feature on-board pulse dampeningefficient mixing. Their pulse-free solvent flow, from analytical to semi-preparative flow rates, makes them ideal for use with highly sensitive detectors.

Designed for use with 2 to 4.6 mm I.D. columns in routine LCLC/MS applications, these pumps 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 phase, improving performancereliability

·                                 Automated seal wash helps extend the primary seal life for reliable operation

·                                 FlexInject manual dual injector module for both analyticalsemi-preparative injections
