Two- or Four-Way Gradient Valve
a two- (standard) or four-way (optional)
low pressure valve, located on the left side
of the instrument, permits users to perform
binary or quaternary elution gradients. the
low pressure valve accommodates up to
four solvents. the binary gradient valve
(Pn 21040143 for PLC 2050 and PLC 2250;
Pn 21040144 for PLC 2500) comes standard
with PLC 2050/2250/2500 Purification Systems.
the optional quaternary gradient valve
(Pn 21040145 for PLC 2050 and PLC 2250; Pn 21040175 for PLC 2500) is also available. for
plumbing connections, refer to
Gradient Valve to Pump Heads on page 39 .
