High Performance Filtration Depth Filter Sheets

Depth filter sheets for biopharmaceutical applicationsFilter sheets are used in biotechnological and pharmaceutical applications for reliable and economical filtration. Pall offers filter sheets with retention ratings ranging from bioburden reduction to coarse filtration. Pall’s advanced pharmaceutical depth filter sheets are available in four different high-performance materials:

Seitz® P-Series Depth Filter Sheets
Seitz P-Series depth filter sheets were especially developed for the strict requirements in biotechnological and pharmaceutical industries. Manufactured with stringent in-process control methods assures constant filtration quality as well as a very high purity of filter medium and in line with the requirements of the pharmaceutical industry.

Seitz® HP-Series Depth Filter Sheets
Seitz HP-Series depth filter sheets are comprised of 2 distinct layers of Seitz P-series depth filter sheets, a more permeable layer followed by a less permeable layer. These performance-enhanced depth filter sheets have been designed for use in low viability, high solids containing applications. As small shifts in process conditions can make dramatic differences in filtration requirements, the flexibility of combining any combination of P-series media in an HP format allows for optimization like never before.

Seitz® Bio-Series Depth Filter Sheets

Seitz Bio-Series depth filter sheets are specially developed from
highly purified natural and modified cellulose fibers and contain no inorganic materials such as diatomaceous earth (DE), perlite or glass fibers. The lack of these inorganic substances significantly reduces the levels heavy metal extractables.

Seitz® K-Series Depth Filter Sheets
Seitz K-Series depth filter sheets are considered a general purpose family of depth filter sheets that are comprised of a balanced composition of cellulosic fibers, diatomaceous earth, and perlite, which enables the creation of a well-defined matrix. Appropriate for many applications less sensitive to ions (such as: Ca, Fe, Al). Those applications requiring decreased levels of extractable ions should reference Seitz P-Series, HP-Series or Bio-Series depth filter sheets.

Seitz® T-Series Depth Filter Sheets
Seitz T-Series depth filter sheets are made from unique combinations of cellulose fibers, diatomaceous earth and perlite. These sheets cover a range of coarse filtration
enabling them to be used to remove the largest of contaminants.

SUPRAdisc™ AKS Carbon Impregnated Depth Filter Modules
The use of bulk Powdered Activated Carbon (PAC) has significant drawbacks relating to the handling of bulk carbon powder, cleaning of process equipment, and time (costs) associated with carbon removal from the process. SUPRAdisc AKS filter media alleviates these concerns by immobilizing activated carbon within a matrix of cellulosic fibers, which is coupled with a downstream filter paper that eliminates any possible particle shedding.

Pall’s filter sheets meet the specifications set forth in the US Code of Federal Regulations Title 21, parts 177.2260 e, f, g, h, i, j, k, l, the materials for all plastic components are listed in US Code of Federal Regulations Title 21, part 177.1520. The Quality Management System of Pall has been certified according to DIN EN ISO 9001 by TÜV Cert (Certification Office TÜV Rheinland, Sicherheit und Umweltschutz GmbH).
