SFT-SeriesII

SFT – Series II Digital Pump

The SFT-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 use of the self-flush head and an one-year warranty ensure years of trouble-free service. Method development is easy with Autoprime™ purging. The SFT-Series II is gives the modern chromatographer solid, reliable performance at a value price. When combined with a SFT-Series III pump, keypad controller, detector, and injector, you have an economical, flexible binary gradient system.

Meets the most demanding applications
The patented low dead volume pulse damper and rapid refill in the SFT-Series II 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.

Reduced maintenance
Seal life is dramatically extended by actively flushing the back of the primary seal with a flushing solution. The result is less down-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 SFT-Series II is a direct replacement for many pumps, including Waters, Shimadzu, and other leading brands.

Performance beyond its price and the security of a 1-year warranty
The use of digital stepper motor technology and the proven single-piston design gives the performance of 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 1-year warranty.

Intended applications

  • Isocratic applications and metering
  • Biocompatible applications
  • Semi-preparative to 40 ml/min
