​RediSep Rf Gold® Diol

High performance media for difficult separations of low- to medium-polarity samples

RediSep Rf Gold Diol functionalized silica gel is less polar and has a higher retention time than normal phase silica gel. Diol media offers an alternative to normal phase columns for difficult separations of low to medium polarity samples. This smaller, spherical media outperforms standard Flash-grade Diol media.
