Hello and welcome to this buy-it-now sale for this Gynotek P580 HDG

Depending on the model, the P 580 pump is intended for the operation exclusively in analytical

or preparative HPLC systems. The pump can be operated either in stand-alone mode or via the

data systems CHROMELEON or GynkoSoft.

The P 580 gradient pump is a zero-pulsation, serial dual piston pump with electronic compressibility

compensation. The two pump heads of the P 580 are serially connected, i.e. the solvent

passes both pump heads - working and equilibration pump head - successively.

Continuous delivery is achieved as follows: The working piston delivers at the appropriate flow

rate while simultaneously filling the serially connected equilibration head. The latter serves as a

reservoir and conveys, while the working piston carries out the suction stroke. The characteristic

feature of the patented isokinetic precompression is the 120 degree overlapping phase of the delivery

strokes of working and equilibration piston. When delivering compressible liquids without

controlled precompression, the pulsation increases with increasing operating pressure, since part

of the delivery stroke is required for the compression of the solvent in the pump head.

Pulsation during the precompression phase is reduced to a minimum by velocity modulation of

the drive. The highly constant delivery is ensured by a patented secondary control system (automatic

compressibility compensation). The flow rate is always kept constant in relation to the atmospheric

pressure.
