The Waters 1525U Binary HPLC Pump is a pre-owned system that exemplifies precision and reliability for high-performance liquid chromatography applications. It offers a programmable flow rate ranging from 0.00 to 5.00 mL/min, adjustable in precise increments of 0.01 mL/min. The pump operates at a maximum pressure of 401 bar, maintaining a pressure ripple below 2% at a flow rate of 0.5 mL/min.
With a flow precision delineated by a standard deviation of just 2 seconds, and a flow accuracy within 2% of the set value, the system ensures consistent performance. The gradient accuracy is maintained to less than 1% between gradients of 10% to 90%, while gradient precision achieves a relative standard deviation of less than 0.5% within the same range. The gradient delay volume is minimized at less than 60 µL without a mixer and under 200 µL with a 50 µL mixer in place.
Designed with operational efficiency in mind, the system incorporates two inline degasser channels to ensure solvent quality. The compact dimensions of the system measure 430 x 610 x 305 mm (HxDxW), and it weighs 27.2 kg. This combination of features makes the Waters 1525U an excellent choice for laboratories requiring dependable HPLC performance.
