Used Lab Equipment

The 1525 and 1525 with EF heads are integrated, high-pressure, binary HPLC pumps that feature on-board pulse dampening and efficient 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 LC and LC/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 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

This can be purchase with a number of optional detectors.
