​RediSep Rf Gold® Normal-Phase Silica

High-performance spherical media for sharper peaks and faster purifications

Chemists choose our RediSep Rf Gold columns to take advantage of its patented silica media. Among these advantages are: outstanding resolution to purify closely eluting compounds and isomers; faster purification runs to save time and solvent; reduced purification times to preserve silica-sensitive compounds; and more concentrated fractions to reduce post-run solvent evaporation time.
