G25 Desalting Purification Cartridges

G-25 desalting purification cartridges is packed with gel filtration chromatography medium with dextran as the matrix , and the separation is achieved according to the molecular size of the separated substancesthrough the molecular sieve effect of the network structure in the dextran During chromatography , molecules larger than the pore size of the gel areblocked out of the gel phase and travel along the gaps between the gelparticles , with the fastest migration speed , so they are eluted first .
