SECcurity isocratic pump
The ideal GPC/SEC pump with highest run-to-run and day-to-day precision of retention times. The optimized design ensures virtually pulse-free and stable solvent flow, with dual floating pistons in series, precisely servo-controlled. This delivery principle allows variable stroke volume optimized to selected flow rate. An inlet-valve electronically activated and synchronized to piston stroke - eliminates vapor formation with volatile solvent. Low operating and maintenance costs - due to long instrument uptime. Versatile wide flow range - up to 10 mL/min, including semi-preparative separations. 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.

SECcurity binary pump
The SECcurity binary pump is based on a high-pressure mixing principle. It is the pump of choice for reproducible gradients and high performance, especially at low flow rates and for high throughput applications. It has an optional programmable solvent selection valve which combines two out of four solvents for utmost flexibility and increased convenience, for example, when flushing the column. The binary pump is also ideally suited to do standard-bore chromatography. Floating pistons with path-of-least-resistance principle ensures highest seal lifetime.

SECcurity quarternary pump
The SECcurity quaternary pump is a pump for low pressure mixing of up to four solvents. The quaternary pump provides highest flexibility in solvent mixing and is recommended for a wide range of research and routine applications, and in the method development area. It ensures virtually pulse-free and stable solvent flow, with dual floating pistons in series, precisely servo-controlled. The variable stroke volume allows pulse-free solvent delivery and efficient mixing. Keeps maintenance to a minimum for lower operation costs by using robust materials such as stainless steel, titanium, gold, ruby, sapphire, ceramics, PEEK and PTFE. Optional active seal wash option for high salt mobile phases to prevent corrosion. Wide flow range of up to 10 mL/min, including semi-preparative separations.
