High Parvovirus Clearance
Pegasus SV4 Virus Removal Filter Cartridges demonstrate highly-efficient clearance of both small ‘non-enveloped’ viruses as well as large viruses.Figure 1 provides an example of its high parvovirus clearance by showing the typical performance of a Pegasus SV4 filter in a 1 g.L-1
BSA solution, as per the PDA’s guidelines:
Retention of porcine parvovirus (PPV, n=4) and small spherical bacteriophage virus (PP7, n=9) by Pegasus Grade SV4 virus membrane in 1 g.L-1 BSA at 3.1 bar (45 psi)1
1PPV retention testing carried out at an independent virus validation test laboratory using 47 mm filter discs
Due to its resistance to flux decay and outstanding throughput properties, typical spikes will not have significant impact on the flux decay of Pegasus SV4 Virus Removal Filter Cartridges.
Constant, Stable Flow-Rate Performance with Outstanding Throughput Capacity
With the need to control the Cost Of Goods Sold being one of the main points of consideration in downstream processing, Pegasus SV4 Virus Removal Filter membrane has been designed to address this need by offering constant, stable flow-rate performance and outstanding throughput capacity, thereby improving process and cost control and enabling maximum virus filtration economy and efficiency.
Highly-Efficient and Economical
Pegasus SV4 Virus Filter membrane also demonstrates highlyefficient clearance of both small ‘non-enveloped’ viruses and large viruses, even showing constant, stable flow-rate performance when used with dilute or complex/concentrated biological fluids.It also offers stable pressure/flux capability in more complex or concentrated feeds, helping to improve virus filtration economy in highly-concentrated protein solutions.Figure 2 shows a typical flux profile for Pegasus SV4 Virus Removal Filter Cartridges when challenged with a monoclonal antibody solution.

Reduces Processing Costs
Pegasus SV4 Virus Removal Filter Cartridges offer a very high filter area per cartridge (2.25 m2
) due to their unique, patented laidover pleat construction which enables significantly more filter membrane to be packed into each cartridge.This helps to maximize process productivity while minimizing process costs, by reducing the amount of filter cartridges required per installation, and helps minimize the hold-up volume of the virus filter system.
