PolyNet PB® Pharmaceutical Grade Filters™
The Next Generation in Pharmaceutical Depth Filtration Technology

Enhanced flow. Lower pressure drop. Extended service life and lower total filtration costs...
These are the benefits of PolyNet PB filter cartridges, the latest advance in depth filtration technology.
The all polypropylene filter is constructed using a proprietary* process that utilizes flow enhancing filter media and an innovative flow pattern. The result is an absolute-rated filter with vastly superior life that provides more cost effective filtration than conventional polypropylene depth filters. PolyNet PB filter
cartridges - the new leader in filtration performance!

ADVANTAGES
Superior Service Life - as much as 4 times greater contaminant holding capacity than 
     competitive filters
All polypropylene depth filter cartridges for broad chemical and temperature compatibility
Ratings from 0.5 - 70 microns to suit a wide range of applications
Absolute-Rated Performance for consistent filtration quality
Provided with Certificate of Quality documenting pharmaceutical testing and lot release criteria

APPLICATIONS
Increasing emphasis on pharmaceutical process economies and end product purity are driving
today’s pharmaceutical and biotechnology industries to high technology filtration products
that offer tangible performance benefits. PolyNet PB filters provide high throughput, enabling
reduced filter change-outs, longer on-stream service life, and significant improvements in
overall process economies.

Pharmaceutical
PolyNet PB filters are ideally suited for general clarifying and prefiltration applications such as
solvent streams, prefiltration of fermentation additives, and parenteral prefiltration. Specific
pharmaceutical process applications for PolyNet PB filters include:

Large and Small Volume Parenterals (LVP/SVP) 
Fine Chemical/Bulk Pharmaceutical Chemical (BPC) 
Antibiotics 
Ophthalmics
Diagnostic Reagents & Buffers
Orals & Topicals
Vial & Stopper Washers
Solvent streams

Biologicals & Bioprocessing
In biological and bioprocess production, Polynet PB filters provide high capacity clarification
of turbid biological solutions, including animal sera, vaccine broths, and plasma fractions.
Effective prefiltration with PolyNet PB cartridges can avoid costly oversized final filter systems.
Specific biological and bioprocess applications for Polynet PB include:

Plasma Fractionation
Vaccines 
Animal Sera & Media Feeds 
Mammalian Cell Culture
Bacterial Fermentation
Downstream Protein Purification
Pre-column clarification (protection)
TFF Protection

Facilities & Plant Services
The PolyNet PB filter’s unique construction provides longer service life in general water filtration service, and in other continuous use applications. Polypropylene depth media offers high contaminant capacity and low extractables in demanding solvent filtration applications. 

Deionized Water
