Excellent low pressure mixing up to four solvents
The optimized design of the 1100 Series quaternary pump ensures virtually pulse-free and stable solvent flow, with dual floating pistons in series, precisely servo-controlled. This design with variable stroke volume allows pulse-free solvent delivery and efficient mixing. An inlet-valve electronically activated and synchronized to piston stroke - eliminates vapor formation with volatile solvents and is maintenance free. With high-speed proportioning valve and pre-configured vacuum degasser, for convenient low-pressure mixing of up to four solvents and highest flexibility in solvent choices.
Ease-of-use - handheld control module lets you enter operating parameters fast, store methods easily and display pressure profile, diagnostics and task-oriented information.
Robust materials withstand most demanding applications - stainless steel, titanium, gold, ruby, sapphire, ceramics, PEEK and PTFE ensure long lifetime.Seal wash option for high salt mobile phases keeps maintenance to a minimum for lower operation costs.
Wide flow range - up to 10 ml/min for broad HPLC work, including semipreparative separations.
More help for GLP - built-in leak and pressure test with graphical presentation of pressure profiles, and early maintenance feedback.
