Devices that can transport biological materials are described. The devices incorporate capillary channeled fibers that can effectively transport living cells as well as other biological materials such as nutrients, growth factors, waste materials, etc. The devices can include a sorptive material at one end of the fibers that can improve transport of materials through the devices. The devices can differentially transport different cell types, particularly when the fibers are held in a vertical orientation. Diagnostic devices that incorporate the capillary channeled fibers are described that can be utilized to separate cell types from one another. Tissue engineering scaffolds that incorporate the capillary channeled fibers are described that can more efficiently transport materials into and out of the scaffolds.

Adsorptive media for chromatography, particularly ion-exchange chromatography, derived from a shaped fiber. In certain embodiments, the functionalized shaped fiber presents a fibrillated or ridged structure which greatly increases the surface area of the fibers when compared to ordinary fibers. Also disclosed herein is a method to add surface pendant functional groups that provides cation-exchange or anion-exchange functionality to the high surface area fibers. This pendant functionality is useful for the ion-exchange chromatographic purification of biomolecules, such as monoclonal antibodies (mAbs).

Disclosed is an equipment including a container filled with chromatography beads for capturing a product present in a process liquid or to prepare them for subsequent use. The equipment also includes a supporting frame standing on the ground and providing support for the container such that the container is spaced above the ground. Outside the container there is provided a lifting system fastened to and supported by the supporting frame and fastened to a part of the container such that the part of the container can be raised by the lifting system relative to the supporting frame and another part of the container. At least part of the lifting system extends aside the container from the bottom to the top of the container.
