Celpure®
Diatomite filter aids for harvesting biological fluids
Our specially treated diatomite High-Purity Filter Aids (HPFAs) are used for solid/liquid separation in biotechnology and pharmaceutical applications. Our Celpure diatomite range is a HPFA specifically designed for the clarification and harvesting of biological fluids, including blood plasma fractionation.
Celpure is produced at our stand-alone, state-of-the-art Lompoc plant in California, US. The process generates a media that surpasses conventional diatomite filter aids in terms of purity, performance and the consistency of the finished product.
Diatomite is powdery, porous and non-metallic, making it ideal for the high-specification needs of the pharmaceutical and biotech sector. It offers enhanced purity and filtration speed over conventional filter aids and enables the removal of microscopically small solids.
Celpure diatomite is now the HPFA of choice in biotechnology and bio-pharmaceutical applications, including blood plasma fractionation and as a filtration-boosting process aid for harvesting and clarifying antibodies and proteins.
Celpure provides a superior and consistent quality to meet this need within this industry. It also complies with the pharmaceutical and biotech industries’ strict regulatory requirements.
Celpure is available in USP-NF grade for use in cGMP processes, and only Celpure and USP-NF grade filter aids meet EMEA Guideline 410/01 Rev 2 and come with BSE/TSE free certification.
All our high purity pharmaceutical filter aids are produced with the most extensive quality system in the filter aid industry. Production is structured to meet the requirements of ISO 9001 as well as the appropriate GMPs and guidance documents.
These quality programmes have been audited and accepted by both traditional pharmaceutical as well as biotechnology-based pharmaceutical producers.
This programme enables the support of customer requirements for:
- Process control
- Documentation
- Quality
- Change control
- Certificate of analysis
When appropriate, compendial certification is documented on the certificate of analysis. Our Regulatory Support Packages are continually updated to meet GMP requirements, guidance recommendations and customer requirements. More details available from our download center.
The documents include information on:
- Manufacturing
- Quality policies
All our high purity filter aids come in a variety of packaging configurations, including non-bulk and semi-bulk. All non-bulk options address USP-NF and pharmaceutical GMP requirements.

Celpure has been awarded the Imerys Pioneer Certificate, our top sustainability rating for products and services, which denotes outstanding sustainability performance compared to the reference on the market. Pioneer certified products provide the highest social and environmental contribution to the downstream value chain, while demonstrating a low environmental impact in their production phase.
Celpure offers key sustainability benefits:
- Ultra-high purity for low extractable applications
- Waste reduction with 30% less filter aid required
- Up to 6x faster filtration rate, translating to shorter filter run times
- Plasma derived biotherapies used in multiple treatments promote the well-being of aging populations
Specially treated diatomite, high-purity filter aids (HPFA) are used for solid/liquid separation in biotechnology and pharmaceutical applications.
In the pursuit of healthy white teeth, Imerys has found that toothpaste that combines kaolin and delicately engineered perlite provides highly effective dental care and meets consumers’ preference for natural ingredients.
The mineral perlite is an effective replacement for microbeads in scrubs and shower gels – not only for its exfoliating performance, but for reducing plastic pollution in oceans.
Mineral-based filters are removing bacteria and other contaminants from drinking water in the developing world.
