P-Series Depth Filter Sheets by Pall Life Sciences Products - Biopharmaceutical Division
The P-series depth filter sheets and modules are available in 10 different types. Due to specific manufacturing methods the distinguishing feature of the P-series is high purity resulting in a very low release of extractables. The depth filter material has been especially optimized to provide a very low release of endotoxins (< 0.02 EU/mL after flushing with 50 L/m2 WFI).
The filter matrix especially developed for the P-series assures retention rates down to 0.1 µm and thus enables an optimal pre-filtration of biological products like no other depth filter for the protection of downstream process steps.
Due to their electrokinetic adsorption potential, positively charged resins increase the retention of smallest particles, such as whole and crushed cells, cell lysate components, endotoxins, DNA and viruses, which usually are negatively charged. Pall P-series depth filters are used worldwide in biotechnological and pharmaceutical applications and provide reliable and economical filtration.
