CRCfilters bulk silica-gel is a high quality, high purity reagent grade media. This silica-gel should be the primary component when compound separation is the goal. Unlike distillation which requires heating the product and exposing it to a high potential of degradation, silica gel can be used at low temperatures. CRCfilters Silica-gel 60A is the product of choice for companies processing pharmaceutical grade essential oils for isolates or simple removal of various colored compounds when integrity of the product must be preserved.
When processing crude oil, use in conjunction with the Pentair Floplus filter cartridge as the secondary purification and isolation step in a packed CRC or standard chromatography column.
