Box is suited for handling liquids in ECOM gradient systems. It accommodates a container for solvent bottles and four-way gradient valve.
Four-way gradient valve is controlled from the pump ECP2200, ECP2300 and gradient box ECB2005 must be ordered with pump.
Pump new sophisticated electronics allows achieving precise low-pressure gradient. i.e. gradual changes of mobile phase composition by mixing up to four liquids at the pump’s entry.
It is also possible to predefine the percentage of composition when using the pump in isocratic mode.
Gradient profile can be defined through the computer or manually, using display and keypad. Up to three 2L and one 1L mobile phase reservoirs may be put into the box.
