Hollow fibre filter modules are particularly useful in tangential flow filtration because processes can easily be scaled-up from small volume applications to full-scale production.

• Hollow fibre membranes are anisotropic in structure
• The filter housings are engineered to handle higher pressures and autoclaving
• Low protein binding increases the product yield of each processing run
• TC filters have ¹/₂" TC/FLL connections and come in three effective lengths

Tangential flow filtration is used in both microfiltration and ultra-filtration applications. Ultra-filtration membranes have a high-density skin layer for less fouling and a fairly open outer support structure for increased filtration rates. Micro filtration membranes have a retention defining microporous outer skin and a more open inner layer for increased filtration with higher recoveries. Single-use eliminates the need for costly stainless steel systems and increases manufacturing flexibility.

Polysulfone (PS) is hydrophilic membrane chemistry with low protein binding properties. It is more resistant to acids, bases and surfactants than other membrane chemistries. PS filters are used in applications like nanoparticle processing and diafiltration.
