Robust pump solutions from UHPLC to preparative clean-up in gram scale
The LC-4000 Series HPLC pumps have 3 operating pressures RHPLC – rapid (700bar), UHPLC – ultra high performance (1300 bar) and preparative (500 bar). Each base has two expansion bays that allow an isocratic pump to be transformed into a powerful gradient solvent delivery system with optional solvent selection for method development.
Options: Isocratic, Binary (two pumps and high pressure mixer) and Quaternary (four solvent gradient mixer with degasser) Flow Rate: Up to 5 mL/min gradient (10mL/min isocratic) Operating Pressure: Up to 700 Bar Degassing: Vacuum (Option) Solvents: 2, 6 or 10
RHPLC, PU-4185 Semi-Micro Pump
RHPLC Semi- Micro Pumps
Options: Isocratic, (two pumps and high pressure mixer) Flow Rate: Up to 4 mL/min Operating Pressure: Up to 700 Bar Degassing: Vacuum (Option) Solvents: 2, 6 or 10
UHPLC, PU-4285 Semi-Micro Pump
UHPLC Pumps
Options: Isocratic, Binary (two pumps and high pressure mixer) Flow Rate: Up to 2 mL/min gradient (10mL/min isocratic) Operating Pressure: Up to 1,300 Bar Degassing: Vacuum (Option) Solvents: 2, 6 or 10
PREPARATIVE, PU-4086/87/88 preparative pumps
Preparative Pumps
Options: Isocratic, (two pumps and high pressure mixer) Flow Rate: Up to 20 mL/min (PU-4086) Flow Rate: Up to 50 mL/min (PU-4087) Flow Rate: Up to 150 mL/min (PU-4088) Operating Pressure: Up to 500 Bar Degassing: Vacuum (Option) Solvents: 2, 6 or 10
Configuration
The unique expansion bays in the pump base can be fitted with plug-in modules to quickly transform a simple isocratic pumping system into a multi-solvent delivery system. Install a second pump (with dynamic mixer) for binary gradients or a quaternary low pressure mixing gradient unit (four solvent), either can be configured with an optional low volume vacuum degasser. A 6 – or 10 solvent selection valve can be added for method development.
Control
The PU-4000 Series pumps are normally used as part of a complete HPLC system, however for applications that require stand-alone operation, each instrument has its own keypad and can be controlled using an RS232 protocol and/or contact closures (TTL) to start and stop the pump.
