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.

SKANDINAVISKA GENETEC AB

Genetec is a member of the same family of companies as Kovalent. Both companies share the same set of values and are in many ways integrated with each other. The main difference between the two companies are their products. Kovalent is involved in system solutions including instrumentation and Genetec is mainly working with consumables. The focus of Genetec is chromatography accessories. You are welcome to visit their state of the art web shop: genetec.se
