Flash column chromatography is a quick and (usually) easy way to separate complex mixtures of compounds. It is widely applied to organic compounds, natural products, biomacromolecule and other active substances.
WelFlash TM SiO2-Ⅱ flash columns use high quality amorphous sphere silica of narrow particle size distribution as packing materials. This provides high resolution of separation and high-pressure tolerance. The polypropylene tube provides great compatibility with various solvents and corrosion resistance. Each column is strictly tested before delivery to ensure high recovery and reproducibility.
