Eaton's BECO PR Range depth filter sheets meet the exact requirements of the pharmaceutical industry and provide high endotoxin retention on a wide range of pharmaceutical products.

The exceptional pure raw materials and the special production method used to manufacture the BECO PR Range depth filter sheets result in a low endotoxin content, < 0.125 EU/ml after rinsing with 1.23 gal/ft² (50 l/m²) of WFI (Water for Injection).

Filter Material
Cellulose with mineral components
Coarse, clarifying, fine filtration; Microbial reduction and removal
FDA, EC 1935/2004, BfR XXXVI/1; Validation Guide available


  • Greatest possible endotoxin retention as well as a maximum germ retention rate
  • A special manufacturing process achieves a low endotoxin content
  • Maximum raw material purity for minimum migration of soluble ions
  • The ideal combination of filtration-active and adsorptive properties ensures maximum reliability
  • Comprehensive quality assurance for all raw and auxiliary materials and intensive in-process controls ensure consistent quality of the finished products
  • Before delivery, the endotoxin content of < 0.125 EU/ml of all BECO PR depth filter sheets is tested with the help of an LAL test. A certificate is available on request

Microbe Reduction and Removal
BECO PR Steril S 100, PR Steril S 80, PR Steril 40 
These specific sheet filter sheets boast high germ retention rates achieved through the fine-pored structure and an electro-kinetic potential with an adsorptive effect. These depth filter sheets are characterized by high endotoxin retention rates and due to their great retention capacity for colloidal components, these filter sheets are particularly suitable as prefilters for subsequent membrane filtration.

Fine Filtration
Eaton's BECO depth filter sheets for achieving a high degree of clarification. These depth filter sheets reliably retain ultra-fine particles and have a germ-reducing effect and are used in practice as ideal prefilters for membrane filters, reverse osmosis systems, and to protect chromatography columns.

Clarifying Filtration and coarse Filtration
These filer sheets offer a large-volume cavity structure and have a high dirt holding capacity for particles and are very suitable for clarifying filtration applications.
