Superior Solvent Delivery Performance
With an automatic pulsation-correction mechanism and high-speed micro plunger driving, LC-20AD 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.
Low-Pressure Gradient Unit
The optional low-pressure gradient unit can be incorporated in the LC-20AD, enabling gradient elution in a compact space with a small void volume. Automatic matching adjustment of the solenoid valve and pump gives concentration accuracies of ±1.0%
A new type of plunger made with a technique that reflects consideration of the material structure and a precise plunger-holding mechanism help to increase the service life of plunger seals and enable stable solvent delivery over long periods.
