Advantages and technical parameters of semi preparative liquid chromatography

preparative liquid chromatography technology is more and more widely used in the separation and purification of samples in pharmaceutical, chemical and biological engineering fields. Typical applications include the purification of synthetic raw materials, the preparation of reference materials, and the purification of final products. The P series preparation pump has reasonable design, stable operation and high performance index. It can meet the production and research needs of users with UV series UV visible wavelength detector (equipped with semi preparation/preparation detection cell) and manual/electric sampling valve and switching valve of rheodyne company in the United States

p230p high pressure constant flow pump

main advantages

double pump heads, series structure - accurate flow

bayonet type 1. Regularly check whether the connecting line of the rear panel of the controller is in good contact with the pump head structure, so that the pump head can be easily loaded and unloaded, which is convenient for maintenance and parts replacement

the floating plunger design makes the pump have the minimum pulsation and greatly extends the service life of the seal ring

provide computer control port, which can be combined and upgraded to high-pressure liquid phase system
