WD-LH20, 1L Sale Purchase

WD-LH20 is modified with hydroxypropyl group on the basis of dextran gel WD-G25. The introduction of hydroxypropyl group makes the filler hydrophilic and lipophilic at the same time, and it can use organic solvents as the mobile phase, which is suitable for the separation and purification of the active ingredients in traditional Chinese medicine as well as for the fine purification of antibiotics and chemical drugs. The separation principle combines the characteristics of molecular sieves, partitioning and adsorption, and can separate molecules with very close structures.
