Depth filters for increased performance and reliability
Our depth filter solutions are trusted for critical filtration applications in the pharmaceutical industry. Designed to deliver superior particle retention, these filters play a crucial role in the clarification, purification, and pre-filtration stages of drug manufacturing.
Available in various formats, including sheets, pads, and lenticular cartridges, these filters are engineered with high-purity cellulose, diatomaceous earth, and other fine filtration media to ensure optimal performance in removing unwanted particulates, endotoxins, and microbial contaminants.
They are widely used in applications such as:
- API filtration
- plasma fractionation
- vaccine production
- cell culture clarification
Ahlstrom’s focus on consistency, regulatory compliance, and adaptability, assures that our depth filters help pharmaceutical manufacturers achieve high-quality filtration results while maintaining process integrity and efficiency.
Depth Filter Media
GXL and PXL depth filter media are high-performance filtration solutions engineered for critical applications across pharmaceutical, biotech, food & beverage, and chemical industries. Formulated with cellulose, resin binders, and an ultra-pure form of Diatomaceous Earth (DE), these filter grades are designed to deliver superior particle retention, clarity, and throughput for use in critical applications requiring extremely low extractable and leachable levels for metal ions. GXL and PXL series deliver reliable filtration results, meeting stringent quality standards and supporting a wide range of critical process needs. In addition to our GXL and PXL media, we offer a wide range of filtration media, including our MicroClear media which utilizes a blend of activated carbon, cellulose fibers, and resin binders.
