AW Celite NF is our high-purity pharmaceutical-grade replacement for conventional, food-grade diatomite filter aids.
Ultra-high-purity diatomite filter aids
AW Celite NF is our high-purity diatomite filter aid, ideal for:
Solid/liquid separation
Produced in accordance with cGMP manufacturing practises
USP-NF compliance
AW Celite NF media is a high-purity pharmaceutical-grade replacement for conventional, food-grade Celite diatomite filter aids. AW Celite NF media is the best choice where a high purity, USP-NF grade direct replacement is needed for conventional food grade Celite filter aids.
AW Celite NF media is produced at our stand-alone Lompoc plant in California, USA, according to a patented manufacturing process. The process generates a media that surpasses conventional diatomite filter aids in terms of purity, performance and finished product consistency.
With the exception of the acid washing step, the AW Celite manufacturing process is similar to that of conventional Celite filter aids. This similarity produces a media that will minimise differences in filtration processes that previously used food-grade diatomite filter aids.
Imerys AW Celite NF media is designed for solid/liquid separation in conjunction with a pressure filtration system. It’s available in a wide range of permeabilities, with the least-permeable grades capable of removing submicron solids in filtration applications.
AW Celite NF media meets the following cGMP requirements:
Regulatory support
Compendial standards
Purity
Manufacturing and process control
