LC2100 High Performance Liquid Chromatograph Tester
Caratteristiche tecniche
★ infusion pump check valve, sealing ring imported from Switzerland original, imported core components to ensure the pump running life and accuracy;
★ Can set automatic pressure protection, ultra low pressure automatic alarm stop, to ensure the safe operation of the instrument;
★ Double plunger floating in series, pump head self-washing function, prolong the service life of the sealing ring, reduce the pressure pulsation, stable and reliable;
Programmed solvent class and compression factor can be automatically compensated; Complete pre-cleaning function for quick solvent replacement;
★ Three flow correction curves and * multi-point parameter correction, to ensure the accuracy of * fluire;
★ High pressure equal degree or gradient mode, can be controlled by software operation, providing work efficiency;
