Pumps

High-performance liquid chromatography (HPLC), ultra-performance liquid chromatography (UPLC), and liquid chromatography-mass spectrometry (LC/MS) systems rely on precise and dependable pumps for solvent delivery and gradient formation. These pumps provide the driving force for mobile phase flow through the chromatographic column, ensuring consistent and accurate results. They operate by precisely metering and mixing solvents at high pressures, enabling the separation and analysis of complex mixtures in applications such as pharmaceutical development, environmental monitoring, and food safety testing. Advanced features, like those found in Agilent's 1260 Infinity II series or Thermo Fisher's Vanquish Horizon systems, allow for sophisticated gradient control, flow rate adjustments, and integration with autosamplers and detectors, enhancing overall system performance and facilitating various chromatographic... + More

Pumps are essential for a wide range of workflows, from simple isocratic separations to complex gradient elution profiles required for challenging analyses. The ability to precisely control flow rate and pressure is crucial for maintaining optimal chromatographic resolution and reproducibility. This precision contributes to accurate quantitation and identification of target analytes in various sample matrices. Whether employed in routine quality control assays or cutting-edge research involving techniques like mass spectrometry, pumps from leading manufacturers like Waters, Shimadzu, and Knauer play a vital role in ensuring reliable and efficient liquid chromatography analyses across diverse scientific disciplines. ALT carries a wide selection of pre-owned, refurbished HPLC pumps. Every unit includes a standard 90-day warranty, with the option to upgrade to a three-year warranty, plus ALT's lifetime support for as long as you own the equipment. Refurbished HPLC pumps from ALT typically cost 50%-80% less than buying new, making it easier for labs to get the equipment they need without straining their budget. - Less
