KrosFlo® MBT Sets
Single-use Module-Bag-Tubing (MBT) Sets for Sterile Fluid Containment Customized for Specific Applications In-process Handling & Separations

Spectrum has expanded the concept of disposability by incorporating irradiated KrosFlo hollow fiber filter modules into sterile KrosFlo EZ-Bag Manifolds to provide a totally disposable process filtration flow-path. Quickly and easily installed on a KrosFlo System for R&D or Process Development, the new single-use flow-path provides a revolutionary approach: pre-packaged, disposable and complete! Customized to your specific application, the Module Flow-paths are available in two different bag configurations and your choice of KrosFlo brand hollow fiber modules.


Providing separate containment of both retentate and filtrate, the 2-Bag Flow-path utilizes an initial "process bag" in the filter loop to concentrate retentate while a second bag collects filtrate. When complete simply clamp off, disconnect and remove the product filled bag for easy transport and storage.


While the retentate is circulating, a third bag can be used to add either more product for large volume concentrations or wash buffer for purification. In these applications, the complete and separate fluid containment includes the feed solution, as well as the retentate and filtrate.
