Silica DE Filter Aide Food Grade for Filtration

Food Grade Diatomaceous Earth (DE) filter aide with a specific particle size to aid filtration.  Low iron and other contaminant content. Use for pre-coating filter paper.

This is the same DE featured on our YouTube videos.  This is calcined DE which will not cause clogging or solvent drag with polar and semi-polar solvents like ethanol.

Ordinary food grade DE is not usually filtration grade as the particle size is too small and will inhibit filtration.  This filtration grade DE will speed up your filtration and reduce paper clogging.
