Botanical Extraction Filter Pack, Includes 90mm Coarse, Medium, and Fine Filters
Botanical Extraction Filter Packs include one pack each of coarse cellulose filter paper (25 micron), medium cellulose filter paper (6 micron), and fine PES filters (0.45 micron) in 90mm diameter.
Sterlitech Offers More Cellulose Filter Papers
Polyethersulfone (PES) membranes are ideal for filtering plant-based extracts because they are hydrophilic, low-protein binding, and resistant to a wide range of alcohols and solvents. Sterlitech PES membranes are also asymmetric; filtering from the more porous (open) side of the membrane allows the filter as its own pre-filter for handling thick slurries. The 0.45 and 0.2 micron pore sizes offered in this section also serve as the industry standard for removing bacteria by filtration.
Our cellulose filter papers are made from natural, refined wood pulp and pre-washed with acid. Their large pore structure makes well-suited for pre-filtering and cold-filtering plant lipids or waxes.
