    Shimadzu LC-20AT HPLC Pump

    Shimadzu LC-20AT HPLC Pump

    Cambridge Scientific ID #'s: 22321, 22320, 22318

    The LC-20AT possesses a high level of stability while maintaining high performance during routine use. The ability to remove pulsations has been improved by modifying the pump-head structure and the flow line.

    Features:

    • Enhanced Solvent Delivery Specifications: Flow-rate accuracy and precision in the micro-flow rate region have been improved with the addition of a new type of check valve and modifications to the solvent delivery control method. Non-polar organic solvents such as hexane can be delivered stably.
    • Improved Durability: New and improved plunger seal materials ensure robust, long-lasting performance. A sapphire plunger optimized according to its crystal structure and a precise plunger-holding mechanism help increase the service life of plunger seals and enable stable solvent delivery over long periods.
    • Space-saving Designs: An optional low pressure gradient valve (LC-20AD/20AT), CBM-20Alite system controller, and a seal wash pump (LC-20AD) can now be installed inside the solvent delivery unit, enabling 4-solvent gradient elution in a compact space. The LC-20AB high-pressure binary gradient pump delivers the performance of two LC-20AD pumps in one compact unit.

    • Flow-rate accuracy: No more than 2% or 2µL/min., whichever is greater (0.01 to 5 mL/min.)
    • Flow-rate precision: No more than 0.06% RSD or 0.02 min SD, whichever is greater
    • Pulsation: 0.3 MPa (for water at 1.0 mL/min. and 7MPa)
    • Constant-pressure solvent delivery: Supported
    • Plunger rinsing mechanism: Manual rinsing or automatic rinsing using optional product
    • Safety measures: Liquid-leakage sensor, high-pressure/low-pressure limits
