This is a refurbished Waters Acquity UPLC H-Class Quaternary Solvent Manager.
The Waters Acquity Quaternary solvent Manager (QSM) is a high-pressure pump that can simultaneously pump four degassed solvents through the Acquity UPLC H-Class system. The pump can deliver gradients in eleven curve shapes (linear, two step, four convex, 4 concave).
The Waters H-Class QSM features four independently controlled solvent channels, allowing for precise control over the composition and flow rate of the mobile phase. The device is capable of delivering up to 6.5 mL/min of each solvent, making it suitable for high-throughput applications. The compact design of the QSM makes it easy to integrate into existing UPLC systems, and its user-friendly interface makes it simple to operate.
