SHP-12 quaternary gradient pump
The quaternary gradient pump uses technology to overcome the challenges of pumping IC/LC solvents at high pressure with low pulsation and is designed to fulfil the needs for low pressure mixing tasks. It contains one high-pressure pump and an integrated LPG mixing block with a 4 channel valve and the new developed mixer, a low-volume mixing device. The integrated degasser and inline filter are completing the analytical IC/HPLC pump and turn this pump into a working horse in the lab. For biocompatible applications or ion chromatography, this pump is also available with a complete metal-free design.
The liquid chromatography quadrilateral pump is a key component of the liquid chromatography instrument. It consists of a single pump and a front-pump proportional valve to form a low-pressure system, which can control up to four mobile phase inputs at the same time. Its advantages are flexible mobile matching ratios, easy switching, simple pump structure, fewer faults and low maintenance costs.
