Jasco LC-4000 series HPLC Pumps

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.

  • 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.
