Introduction to the Pump

The Pumps comprise one pump head unit with an optional solvent cabinet, a
vacuum degasser (optional for the isocratic pump), and a multi-channel gradient
valve (MCGV) for quaternary pumps, or an optional solvent selection valve (SSV)
for isocratic pumps. The combination of the pump head assembly and
high-speed proportioning MCGV with a possible connection up to four different
solvents in quaternary pumps provides gradient generation by low pressure
mixing. The combination of the pump head assembly and SSV in isocratic pump
provides opportunity to make a choice between three different solvents. A
solvent cabinet provides enough space for eight one-liter bottles. The Active Seal
Wash (ASW) and Active Inlet Valve (AIV) options are available for quaternary
pumps when concentrated buffer solutions are used. The Bio-inert pump is
optimized for these conditions, thus is always equipped with ASW and AIV.
