LC-20AD

General Description

The LC-20AD Parallel Double Micro Plunger Type Pump offers the most stable solvent delivery performance in the world. With an automatic pulsation-correction mechanism and high-speed micro plunger drive, it achieves pulse-free solvent delivery. Improvements in solvent-delivery control firmware have significantly improved performance in the micro-flow-rate range below 50 �L/min 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 seal plunger 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. Specifications: Plunger capacity 10�L Maximum discharge pressure 40MPa Flow-rate setting range 0.0001 to 10.0000 mL/min. Flow-rate accuracy No more than 1% or 0.5�L/min., whichever is greater (0.01 to 2 mL/min.) Flow-rate precision 0.3% max. (RSD: 0.1% max.) Pulsation 0.1 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 Operating temperature range 4oC to 35oC Dimensions, weight 260 (W) x 140 (H) x 420 (D) mm, 10 kg Power requirements 100 VAC, 150 VA, 50/60 Hz GRADIENT SYSTEM Low pressure mixing, maximum 4 solvents High pressure mixing, 2-3 solvents, mixing accuracy 0.5% max.
