LC-4000 High Performance Liquid Chromatograph

P4000 High Pressure Infusion Pump

Introduction
P4000 infusion pump - high precision, high stability, high efficiency.
P4000 infusion pump is widely used in various fields of chromatography analysis. The experience and technology that P4000 infusion pump has obtained is applied to the development of new technology, which constantly enrich various functions that experiment requires .

Features
 It adopts patent and exclusive technology of static motor control circuit, which can make the motor control signal automatically get feedback and track, improving the motor control accuracy and ensuring the reliability and stability of the pump.
 Pump form: double-plunger reciprocating series or parallel
 The patented technology of floating self-aligning seal technology andpump head self-cleaning extend the service life of the seal, and ensure the instrument is durable and cost-effective (online plunger seal cleaning (optional)).
 Convenient and easy flow and pressure correction ensure high accuracy and stability of the instrument.
 Two kinds of gradient operation program design are adopted: with linear gradient and step gradient to choose;
 Programmed solvents and compression factor can be automatically compensated.
 Complete pre-cleaning function can facilitate the replacement of the fast solvent.
