The Prep HPLC columns are packed with high quality silica particles. They provide high resolution preparative separations with 10 or 15 μm particles. As the price of the stationary phase drastically increases when the particle size decreases, this allows to optimize the cost of the purification. The Prep HPLC columns perfectly match with the BUCHI Reveleris® Prep system and offer the ideal solution for a fast and cost effective purification.
