Systemy podawania eluentu

The pumps belonging to the JASCO LC-4000 series make possible the solution of analytical, semi-preparative or preparative chromatographic tasks. A wide range of optional accessories (valve system, degasser, mixer, etc.) can be built in the newly-created expansion bays of the pump case, which provides many possibilities for building isocratic and gradient eluent delivery systems. All the isocratic pumps can be built further into gradient pumps. The instruments have a built-in control unit which can be programmed with keys. On the two-line LCD screen the set flow rate, the current pressure value, the adjustable pressure limits, as well as the current program status can be read. With the JASCO ChromNav2 chromatography software all the functions of the pumps can be controlled. The long-term, maintenance-free operation is also promoted by the built-in rear washer system, which increases the piston seal lifetime by preventing the salt precipitation.
