PU-2080 general information
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 µL 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.
The PU-2080 can easily be interfaced with the JASCO HPLC system using the EZChrom Elite™ Software. The EZChrom Elite software offers full automation of the JASCO HPLC system including the PU-2080 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. Two pumps and other components can be stacked to comprise a system requiring minimal bench space in the crowded modern laboratory.
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.
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.
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. Full PC control is available if desired.
