Agilent SD-1 Solvent Delivery Module Features, Specifications, and Ordering Details To achieve high quality HPLC separations, solvent flow rates must be accurate and reproducible. With software-controlled, independent piston design, the Agilent SD-1 Solvent Delivery Module meets these exacting requirements. To maximize flow reproducibility, a pressure transducer in each pump head provides instant flow, and pressure feedback to the drives. The dual motor, high resolution drives ensure supremely accurate solvent delivery and the pulse free pump design extends column life. An easy change of pump heads gives flow rates from 0.01 mL/min to 800 mL/min, up to 6,000 psi, showing that the SD-1 is ideal for use with analytical and preparative systems, providing seamless scale-up that is simple to achieve and economical in operation. Features • Outstanding retention time stability, day in and out is ensured by totally pulse-free flow • Maximized versatility as isocratic and binary gradient configurations or injection pump • Easy scale-up with flow rates from 0.01 mL/min to 800 mL/min using three different pump head configurations up to 200, 500, and 800 mL/min at pressures up to 6,000 psi • Highly accurate flow rates delivered by a unique microprocessor-controlled rapid dual-drive and parallel pump heads with high-speed feedback to compensate precisely for refill and solvent compression effects • Easy and faster scale up of your analytical method. The SD-1 pump is designed with scale-up in mind. The unique design allows an accurate gradient to be generated at any flow rate from 0.01 mL/min to 200 mL/min without any change of pump heads • Extended column lifetime saves expensive preparative columns from the constant pressure-pulse pounding typical of other
