Research and development facility in Glenview, Illinois, USA


The regional head office for North and South America in Glenview, Illinois has developed a state-of-the-art research and development facility to support and collaborate with users of Planova™ filters in the Americas and throughout the world.

Phage laboratory and filtration suite

The phage laboratory is a Biosafety Level 2+ facility held under negative pressure and features a biological safety cabinet for maximum safety when working with the BSL2 host agent, Pseudomonas aeruginosa.

Phage laboratory capabilities

  • Scalable phage production process
  • Capacity for producing hundreds of milliliters of high-titer PP7 stock
  • Filtration setups available at our facility for small-scale phage clearance studies with automated pressure and throughput data collection
  • Phage log reduction value (LRV) results available in 1 to 2 days

PP7 bacteriophage as a model for mammalian virus filtration

Bacteriophages provide unique systems for evaluating virus removal in filtration processes. Structurally similar to mammalian viruses, bacteriophage stocks can be produced with significantly higher titers and require shorter assay time.
PP7 phage is small, non-enveloped, and infects the bacterial host P. aeruginosa. Based on its size and shape, PP7 phage is an excellent model for small, non-enveloped viruses such as parvoviruses.

Phage clearance study on Planova™ filters

The following clearance study data using 5 g BSA/L feed spiked with 0.1% PP7 on Planova™ 15N, 20N, and BioEX filters demonstrate the suitability of our PP7 phage stock as a model for PPV.

  • Minimal flux decay, indicating the clarity of the stock solution
  • Comparable, high removal based on high load titers and LRV
  • Monodispersion of PP7 phage particles, as indicated by the lack of removal on Planova™ 35N filters
