The Model 501 is a high performance, compact solvent delivery module
that has been designed to compete with the most expensive pump systems
on the market in reliability and performance without the high cost.
A dual piston design with solvent compressibility feedback assures virtually
pulse-free and accurate solvent delivery. The Model 501 has all of the
features of the Model 500, but without gradient programming capability.
It may be used as an economical stand alone pump for isocratic operation,
or in conjunction with a Model 500 for gradient operation.
