Abstract
A manifold segment is provided for tangential flow filtration apparatus. The manifold segment includes a fluid feed conduit, a retentate conduit, a filtrate inlet and a filtrate outlet. An adaptor manifold is provided which directs filtrate from the manifold segment into a tangential flow filtration module and directs filtrate from the module into the manifold segment. Filtrate introduced into the tangential flow filtrate module reduces pressure drop across a filter layer in the module.
