Blood Product Filtration
Tangential flow filtration (TFF) cassette membranes are the preferred choice in applications, such as blood product filtration, that require gentle processing. There are four cassette formats for ultrafiltration (UF) and microfiltration (MF) applications — Centramate™, Centrasette™, Maximate™ and Maxisette™.
Filter Cartridges for Blood Product FiltrationFluorodyne® II Hydrophilic PVDF Filter Cartridges
Pall Fluorodyne II filter cartridges feature a unique hydrophilic modified polyvinylidenefluoride (PVDF) membrane with ultra low binding properties, broad chemical and temperature resistance, and higher flows than competitive PVDF or other membrane cartridges.
PreFlow™ Filter Cartridges
Supor EKV polyethersulfone membrane cartridges are validated, 0.2 μm sterilizing-grade blood product filters with a unique combination of Pall Ultipleat filters and optimized built-in prefiltration to give longer filter life and lower filtration costs.
Pall Ultipor VF Grade DV50 virus removal filters are a robust means to remove viruses from blood products by microfiltration, while permitting enhanced transmission of proteins. SBF Junior Style pleated membrane mini-cartridges are designed for small-scale qualification and validation studies and for small process batches up to 10 – 20 liters.
Pall Ultipor VF grade DV20 filter cartridges are integrity-testable, direct flow filters for size exclusion removal of viruses as small as 20 nm from blood products.
Pall Ultipor VF virus removal filter cartridges feature innovative hydrophilic PVDF microporous membranes to remove significant levels of viruses from blood products, while enabling > 95% transmission of proteins up to 300 kD or larger.
Depth Filteration Products
Disposable depth filter modules for medium to large scale process filtration.
The Supradisc module design concept combines the advantages of conventional depth filter sheets with the positive features of enclosed filters. Each module consists of three major components: individual filter cells or lenses, a tubular center core, and adapters.
The distinguishing feature of the P-series is their high purity resulting in a very low release of extractables as well as an extremely low endotoxin content (<0.06 EU/mL prior to rinsing with 50 L/m2 WFI).
Capsule Filters for Blood Product Filtration
Validated, 0.2 μm sterilizing grade filters with built-in prefiltration to give longer filter life and lower filtration costs.
Designed to provide choice, cost effectiveness and flexibility, while ensuring ease of use for the operator. Disposable filters can help eliminate cleaning problems, especially where blood products are filtered.
Pall’s Mini Kleenpak sterilizing capsule blood product filters are compact pharmaceutical-grade capsule filters featuring very low hold-up volumes.
The Novasip DV20 grade capsule filter utilizes an Ultipor VF-grade DV20 grade pleated membrane cartridge to remove parvoviruses and other viruses as small as 20 nm from protein solutions up to 5 – 10 liters.The Novasip DV50 grade capsule filter incorporates an Ultipor VF DV50 grade Ultipleat membrane cartridge that can remove viruses 40 – 50 nm and larger from blood products.
Pall Kleenpak capsule filters with hydrophilic PVDF Fluorodyne II membrane are rugged, self-contained sanitary filters designed for small-batch sterile filtration of most pharmaceutical solutions.
