Wide Range of HPLC Pumps

The wide range of LC-2000 HPLC pumps is extremely versatile offering both isocratic and gradient operation at a variety of scales from 1uL/min to 100mL/min. All of the pumps featured here can be used as part of a complete JASCO HPLC system or can be added to your existing system with programming using keypad control and simple contact closure communication to start timed programs. JASCO pumps are used for a wide variety of non-HPLC applications; please let us know if you have a special application we can help with.

PU-2080 Analytical Isocratic HPLC Pump

The 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 delivers 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.

• Flow range 1 μL/min to 10 mL/min
• Better than 0.1% flow rate precision at 0.2 ~ 5.0 mL/min
• Versatile time-based programming of high pressure binary and low pressure ternary gradient elution
• HG-2080 binary gradient HPLC pump – gradients from below 100uL/min to 10mL/min
• Ceramic plungers with an automatic plunger backwash system for a long, maintenance-free lifetime
• Optional RS232 control

PU-2089 Quaternary Gradient HPLC pump

Quaternary gradient pump with built-in degasser. This compact design is used in the JASCO gradient HPLC system, but can also be added to your existing HPLC system with simple keypad programming and contact closure to start the time program.

• SSQD pumping method for the most reliable, accurate and stable solvent delivery
• Built-in proportioning valve and degasser for four solvents gradients
• Flow range 1 μL/min to 10 mL/min
• Ceramic plungers with an automatic plunger backwash system for a long, maintenance-free lifetime
• Keypad programming for stand-alone applications
• Optional RS232 control

PU-2085 Semi-Micro HPLC Pump
Ideal for low flow rate semi-micro and LC/MS applications

Micro delivery pump for low flow rate applications using 1mm, 2mm and 4.6mm ID columns. The PU-2085 uses micro components in the fluid delivery for accurate metering and can be used for isocratic operation to a few uL/min and gradients from 30uL/min.

• Flow rate range: 1 uL/min to 4.0 mL/min
• Flow rate precision: better  than 0.1% (Relative Standard Deviation) from 0.05 - 1.0 mL/min
• Max. pressure: 35 MPa constant pressure mode
• Keypad programming for stand-alone applications
• Optional RS232 control
