Biotage® Work-up Products

Celite* cartridges are used as a filtration device for removal of “tar” and particulate materials (e.g. catalysts, as first- stage work-up following organic synthesis). The cartridges contain an inert Celite material, a modified diatomaceous earth, with an optimized particle-size distribution for flow-through processing. The cartridge holds up catalysts such as insoluble metal oxides and Pd/C, providing filtrates for subsequent work-up. The retention of the catalyst in a cartridge format minimizes safety issues and cross-contamination, a common problem when the catalyst is captured in an open filtration device such as a sintered funnel.
