PU-2085 Micro
Fast becoming the standard for LC-MS applications requiring low flow-rates couple with high flow reliability, the PU-2000 series of pumps can be controlled by Analyst, Masslynx and XCalibur. The pump provides extremely consistent solvent delivery via SSQD (Slow Suction Quick Delivery).
The pump may be operated in normal operation mode or program mode. Normal operation mode offers a constant flow rate or pressure. In program mode, selection of composition, flow rate, solvent selection valves, and event relays can be performed according to a user-defined time program. For gradient pumping, both high-pressure (mixing) and low-pressure (mixing) methods are available. The appropriate method depends on the system being used.
Ideal for 1-2 mm columns and low flow rate gradients for LC/MS flow range 1 µl/min to 4 ml/min.
