The life time of the multi-channel gradient valve can be increased by regularly
NOTE
flushing the valve, especially when using buffers. If using buffers, flush all
channels of the valve with water to prevent precipitation of the buffer, otherwise
salt crystals could drop into an unused channel and form plugs that may cause
leaks of that channel. Such leaks will interfere with the general performance of
the valve. When using buffers in combination with organic solvents, it is
recommended to connect the aqueous solutions/buffers to one of the bottom
ports (A and D) and the organic solvent to one of the upper gradient valve ports.
It is best to have the organic channel directly above the buffer channel
(e.g., A - buffer, B - organic solvent).

Switch off the pump at the main power switch.
Open the doors of the module.
Use an optional solvent shutoff valve or lift up solvent filters in solvent reservoirs for avoiding
leakages.
