Seitz® P-Series Depth Filter Sheets

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

The P-series depth filter sheets are available in eleven different grades. Due to specific manufacturing methods, the distinguishing feature of the P-series sheets is their high purity resulting in a very low release of extractables as well as an extremely low endotoxin content (< 0.06 EU/mL prior to rinsing with 50 L/m2 of WFI). As part of Pall’s standard flushing recommendations, further reduction of extractable and endotoxin levels can be achieved (as documented in Pall Validation Guide reference USTR 2366).
