The 1260 Infinity Preparative Pump is suitable for isocratic and gradient separations. It delivers a stable and reproducible flow at both low and high flow rates; the addition of a second pump will allow you to assemble a high-pressure gradient system. The 1260 Infinity Preparative Pump is a core component of the Agilent Preparative Scale Purification System which is suitable for semi-prep and preparative separations.
