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.
