Series II Pump
Meets the most Demanding Applications
The patented low dead volume pulse damper and rapid refill make this single-piston pump virtually pulse-free. It meets the requirements of the most demanding detectors.
Analytical and Preparative Separations
Flow rates from 0.001 to 5 mL/min.; 0.01 to 10 mL/min.; or 0.1 to 40 mL/min. are available.
Material Compatibility for All Applications
Available in either traditional 316 stainless steel or biocompatible PEEK™ (polyetherether ketone) for metal-sensitive applications. Choose the material best suited for each application.
Seal life is dramatically extended by actively flushing the back of the primary seal with a flushing solution. The result is less down-time and reduced operating expenses. The self-flush is automatic; just change the flushing fluid weekly. Seals can be changed in five minutes without tools.
Easy Solvent Changes
Autoprime™ one-button purging makes it easy to prime or purge the pump.
Works in Your Existing System
The Series II is a direct replacement for many pumps, including Waters, Shimadzu, and other leading brands.
Performance Beyond Its Price
The digital stepper motor technology and the proven single-piston design perform like the most expensive pumps at a fraction of their cost. The operating cost is lower too, due to the simplicity of the design and fewer number of parts required. It’s so reliable it carries a three-year warranty.
The Series II pump consists of a series of modular subassemblies packaged to meet basic metering and chromatography application requirements.
The extensive use of digital logic and a micro-stepped motor allow for precise and flexible control. The user interface consists of an LED display and keypad. The self-flush head and a three-year warranty ensure years of trouble-free service. Method development is easy with Autoprime™ purging.
The Series II gives the modern chromatographer solid, reliable performance at a value price. When combined with a Series III pump, keypad controller, detector, and injector, you have an economical, flexible binary gradient system.
