HPLC Solvent Delivery Modules

The ProStar series offers fully integrated, fully automated, modular HPLC pumping systems for every application and budget.

For Analytical Applications:

For Preparative Applications:

From isocratic to quaternary, these compact pumps were designed for easy operation and maintenance. Featuring pump stroke counters and automatic leak tests, ProStar pumps help your laboratory meet established Good Laboratory Practice (GLP) protocols.

ProStar solvent delivery systems offer pump heads in a choice of flow range or material, including stainless steel, titanium, and PEEK. And regardless of the flow range, features like pressure transducer feedback, automatic compressibility, and built-in pulse dampers ensure smooth and precise operation -- in either isocratic or gradient mode.

ProStar 220/230/240 Ternary Solvent Delivery Module

Choose the 220 (Isocratic), 230 (Ternary) or 240 (Quaternary) best suited to your laboratory's needs. All of these models feature a patented pump design that offers unequaled reliability and ease of use.

Cost-Effective

• Time and money saved -- Neither vacuum degassing nor helium sparging are needed.
• Pump cavitation eliminated -- Patented pump design features exclusive mechanical inlet valve, rapid fill stroke, and high pressure mixing.
• Over 99% uptime achieved - Maintenance or repair rarely needed. Pump stroke counter allows scheduling of routine maintenance.
• Extremely easy routine maintenance -- With multilevel diagnostics and accessible components, pumps can be overhauled in less than 30 minutes.

Peak Performance

• Gradient pumps offer selectable one-, two-, or four-stroke proportioning is available to optimize gradient precision on long, shallow gradients while minimizing gradient delay volume on steep, fast gradients.
• Reliable results -- Intelligent design, including electronic flow and in-line, high-speed proportioning valves, assures accurate and reproducible results.
• GLP compliance -- Run-and-error logs maintain a complete audit trail of operating parameters, set points, errors, and faults.
• Built-in automations -- Up to five methods can be built and stored at the pump. Choose the appropriate method with a single keystroke.
