This system is widely used for the extraction and purification of proteins, amino acids, alkaloids, ginkgo flavonoids, bamboo leaf flavonoids, phenols, aldehydes, vitamins, enzymes, monosaccharides, polysaccharides, and plant active ingredients. With a rational diameter-to-height ratio and precise inlet/outlet fluid distributors, equipped with an automatic filling system and compressed air interface, the system ensures optimal column packing and regeneration effects, providing a reliable guarantee for efficient separation. It can operate under atmospheric pressure, allowing the mixture to pass through in one go, obtaining multiple components with high separation purity.
