Product Overview
The Waters 1525EF Binary HPLC Piston Pump is a high-performance, dual-piston reciprocating pump engineered for precision solvent delivery in analytical and preparative high-performance liquid chromatography (HPLC) systems. Manufactured by Waters Corporation, a global leader in separation science instrumentation, the 1525EF utilizes a binary gradient configuration that independently proportions two mobile phases for accurate, reproducible gradient formation. The pump employs a dual-piston, single-stroke reciprocating design with advanced cam-driven mechanics to deliver pulse-free, stable flow across a broad flow rate range. Its robust construction and precise metering capability make it a critical component in pharmaceutical QC laboratories, contract research organizations, and industrial analytical facilities where chromatographic integrity and long-term reliability are paramount.
