The preparative Pump 80P delivers stable and precise solvent flow for semi-preparative as well as preparative HPLC applications.By adding one or more additional pumps, binary, ternary or even quaternary high-pressure gradient systems can be easily configured. The pump can also be equipped with a binary or ternary gradient valve block to configure cost-effective low-pressure gradient systems.Exchangeable pump heads for flow rates up to 1 000 ml/min and pressures up to 40 MPa make it possible to easily optimize the pump to changing performance requirements and allow simple maintenance.The integrated automatic recognition of the pump head with RFID technology allows fast adaptions of the pump for various applications.Available in stainless steel or biocompatible titanium versions, the pump heads enable a wide range of applications.Key featuresDual-piston technologyLiquid transport with low pulsation, stable flow rate and high flow accuracyInternal controlling for programming binary to quaternaryHPG system: Up to four pumps can be combinedLPG system: Connection of a binary or ternary LPG valve blockUltra-precise gradient mixtures throughout entire flow rangeHigh physical and chemical stabilityDirect pump control via analog and digital signals
