P-series

Seitz™ P-series depth filter sheets were specifically developed for the strict requirements in biotechnological and pharmaceutical industries. Manufactured with stringent in-process control methods assures consistent filtration quality, a very high purity of filter medium, and alignment with the requirements of the pharmaceutical industry.

Bio-series

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 of ash and heavy metal extractables.

HP-series

Seitz™ HP-series depth filter sheets are comprised of two distinct layers of Seitz™ P-series depth filter sheets; a coarser layer upstream followed by a finer layer downstream. 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 cause dramatic differences in filtration requirements, the flexibility of combining any combination of Seitz™ P-series media in a Seitz™ HP-series format allows for improved process optimization.
