Silica Filter Aide Food Grade for Filtration

Regular price $125.00 Sale

Food Grade Diatomaceous Earth (DE) filter aide.  This DE has a specific particle size for filtration.  Low iron and other contaminant content.  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.

Comes in Gallon buckets.

Shipping is included.  Pallet loads available at discounted prices.  Other PH also available in bulk loads.
