The JASCO Model PU-2080 is a compact full function HPLC pump designed to meet the most critical of modern laboratory demands. The SSQD (Slow suction, Quick delivery) pumping system is ideal to assure the most reliable and pulse free solvent flow. The simple design utilizes only 2 plungers and 2 check valves for optimum reliability and ease of maintenance. Performance is exceptional with flow rate precision over the flow rate range of 1 ml to 10 ml per minute. Versatile programming capabilities allow sophisticated time-based programs of isocratic, binary or ternary gradient elution, flow rate, solvent selection, etc., meeting the numerous requirements for applications in various fields.

PU-2080 Plus compact-sized HPLC pump

The size of the analytical HPLC pump is a mere 15 cm wide and 15 cm high. Two pumps and other components can be stacked to comprise a gradient HPLC system requiring minimal bench space in the crowded modern laboratory.

HPG-2080 High Pressure Binary Gradient Pumps

Combine two PU-2080 pumps to create a high performance high
reliability gradient system. Also for high pressure ternary gradients

High pressure mixing is stil the best way to make gradients.

• fast responsive gradients
• negligible dead volume
• tailored mixing according to flow-rate and solvent viscosity

Using the dynamic mixer the PU-2080-HD offers a very flexible gradient pump from 10 ml/minute to down below 20µl/minute without compromising dead volume or mixing efficiency.

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.

Utilising 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 by 2 pumps or low pressure gradient operation using one pump and proportioning valve without need of a system controller. The stand alone PU-2080 can even control a 6-solvent selection valve to allow control of complex applications such as Amino Acid Analysis. Of course full PC control is available.
