Featuring a new powerful LCD control pad, the YL911x Plus range of pumps provides quick setup status with finger touch controls enabling you to monitor the pump without any additional software. The YL9110 Plus Quaternary Pump also enables the highest repeatability with a more stabilized baseline when it is in the gradient condition.

Smart Control
Setting any factors or by simply pressing the Purge button, you can easily set the flow rate or solvent composition. Also, you can monitor the pressure and status of pumps.

Fully Automatic Prime
A simplified system means you only need to set the solvent composition and press Prime On button. The system automatically flows each solvent at 100% to remove bubbles or change the solvent in the flow path and then get back to the set composition rate to be ready.
