Shimadzu LC-20AT HPLC Pump, Shimadzu Excellence in Science (CAT#: STEM-C-0229-LGZ)

Highlights

1. Enhanced solvent delivery specifications: By adding a new type of check valve and modifying the solvent delivery control method, the flow accuracy and precision in the micro-flow area has been improved. Non-polar organic solvents, such as n-hexane, can be delivered stably.
2. Improved durability: New and improved plunger seal material ensures strong, long-lasting performance. Crystal structure-optimized sapphire plungers and precise plunger retention mechanisms help increase plunger seal life and enable stable solvent delivery over long periods of time.
3. Space saving design: An optional low pressure gradient valve (LC-20AD/20AT), CBM-20Alite system controller and seal wash pump (LC-20AD) can now be installed in the solvent delivery unit to enable 4 solvent gradients Elute in a compact space. The LC-20AB high pressure binary gradient pump provides the performance of two LC-20AD pumps in one compact unit.

Cat Number: STEM-C-0229-LGZ
