E-Series Depth Filter Sheets by Pall Life Sciences Products - Biopharmaceutical Division

Introduction
E-Series is a new filter paper with depth filter properties for use in the pharmaceutical industry. It substitutes for conventional filter paper in solid and liquid separation or clarifying filtration. Compared with conventional filter paper, the E-Series has the following advantages:

• Better clarifying results due to depth filter properties
• Better mechanical stability due to higher wet strength
• Very easy discharge of proteins or protein cake due to special surface treatment

The high wet strength combined with the low weight per area allows for the best separation results, even in pre-coat filtration for the separation of pastes.

Features and Benefits
E-Series is a filter paper with depth filter properties, which is obtained by the thickness of the filter medium. In comparison with filter papers having the same retention rates, the E-Series provides significantly better clarification than conventional filter papers.

Advantages

• Safe operation due to high wet strength
• High mechanical stability (filtration at high operating pressure is possible)
• Easy removal of protein cakes due to the very smooth, low adhesive surface
• Higher clarity and retention due to the depth filter properties
• High dirt-holding capacity
