Biotech Fluidics announce the ASI 540 – an affordable, standalone solvent delivery pump - design optimized for liquid chromatography applications.

All models of the ASI 540 pump range feature an intuitive touchscreen display that enables full control of the pump functions, flow rates, and gradient programs. ASI 540 pumps can also be remote controlled. The pump is available in several different models for UHPLC, HPLC, semi-preparative, preparative, and flash chromatography, together covering liquid flow rate ranges from 0.5 µL/min to 300 mL/min. With pump heads in stainless-steel or biocompatible PEEK, the ASI 540 pump can withstand pressures up to 15,000 psi (1050 bar) while also being compatible with many solvents and requirements.

While the ASI 540 pump is extremely easy to use, it also includes advanced functionality for experienced separation scientists. The ASI 540 pump includes useful features such as a patented floating pump seal that stays perfectly aligned with the piston for reduced wear and longer seal lifetime. The pump head is also self-priming and comes with an integral purge function for rapid solvent changes. Flow precision using an ASI 540 pump exceeds 0.25% within the entire flow rate range and pulsations are below 1%.

Each ASI 540 pump is designed for easy maintenance while also being RoHS compatible and CE certified. All user serviceable components are accessed via the front panel, and the cartridge seal design makes seal replacement straightforward.
