Used Lab Equipment

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.
