The JASCO Model PU-2080-HD is a compact HPLC Binary-High-Pressure-Gradient-Pump designed to meet the numerous requirements for a wide range of research and routine gradient applications.
The pulse-free and stable SSQD (Slow suction, Quick delivery) pumping system is ideal to assure the most reliable solvent flow.

The dynamic high pressure mixer enables high flexibility in solvent choices.

The PU-2080-HD can easily be interfaced with the JASCO HPLC system using the ChromPass Software. The ChromPass software offers full automation of the JASCO HPLC system including the PU-2080-HD and other components, along with an audit trail with enhanced GLP compliance

Compact-sized HPLC pump

The size of the pump is a mere 15 cm wide and 15 cm high. The PU-2080-HD and other components can be stacked to comprise a system requiring minimal bench space.

Excellent pump performance

The SSQD (Slow suction, Quick delivery) pumping method ensures the most reliable, accurate, and stable solvent delivery possible. A guaranteed flow rate precision within 0.1% assures good reproducibility of retention time. Pulse-free flow assures maximum detector sensitivity.

Extreme durability

Utilizing ceramic plungers and an automatic plunger cleaning system assures a long, maintenance free pump life. Diaphragms located behind the plunger seals and a pair of check valves act as pumps for cleaning the plunger surface, thus avoiding the precipitation of salts from buffer solutions during intermittent operation.

Full programmability

Stand-alone front panel programming of 10 files with up to 64 steps/file is provided eliminating the need for external computers or system controllers. Built-in program allows either high pressure gradient operation or low pressure gradient operation without need of a system controller. Full PC control is available if desired.
