Wide Range of Solvent Delivery Systems

PU-2080 Analytical Pump
Compact full function HPLC pump

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.

• Delivery mode: Constant flow/constant pressure, selectable constant flow mode
• Flow rate range: 1 uL/min to 4.0 mL/min
• Flow rate setting: 1 uL/min to 4.0 mL/min with 1 ul steps by Ten key operations
• Flow rate precision: Less than 0.1% (Relative Standard Deviation) from 0.05 - 1.0 mL/min
• Flow rate accuracy: +/-2% of setting or +/-2 ul/min whichever is greater at 0.05 - 2.0 ml/min, 0 - 35 MPa
• Max. pressure: 35 MPa constant pressure mode
• Pressure range: 3 - 35 MPa
• Pressure setting: Adjustable in 0.1 MPa increments by ten key operation
• Pressure limit: Settable max, and min pressure limit in 0.1 MPa increments
• Maximum pressure: 0 - 50 MPa
• Minimum pressure: 0 - 50 MPa
• Pressure sensor: Flow through type strain-gauge transducer

PU-2086 Semi-Prep/PU-2087 Preparative Pumps
Excellent pump performance in isocratic or gradient modes

In addition to the Model PU-2080 analytical pump, JASCO offers two preparative scale HPLC pumps. The model PU-2086 covering flow rates from 0.001 to 20.000 ml/min. and PU-2087, covering the flow rates from 0.001 to 50.000 ml/min. Both models can be used in isocratic or gradient modes with the same precision and reproducibility of many analytical scale pumps.

• High precision and reproducibility for isolation and purification requirements·         
• Dual plunger design optimal for high-volume delivery eliminates pulsation
• Flow range to 20 mL/min (PU-208Flow range to 50 mL/min (PU-2087)
• A recycle valve is provided for convenient recycling methods

PU-2080i/PU-2089i Inert Pumps
For biological separations without metallic material contact

JASCO offers the PU-2080i and PU-2089i that are manufactured by using polyetheretherketone (PEEK) instead of metal parts which may become exposed to fluids. This allows analyses without concern about sample decomposition or absorption caused by metal.
