The LC-20AD offers the fastest solvent delivery performance in the world. With an automatic pulsation-correction mechanism and high-speed micro plunger driving, it achieves pulse-free solvent delivery. Thanks to improvements in solvent-delivery control firmware, solvent-delivery performance in the micro-flow-rate range below 50 μL/min has been significantly improved.
