AcroPrep 24-well clarification and sterile filtration plate, Depth filter plus 0.65/ 0.2 µm Supor EKV PES membrane. Pall’s clarification and sterile filtration AcroPrep 24-well filter plate can both clarify and 0.2 μm sterile filter in a single device and workflow step. With either a vacuum manifold or centrifuge, high density cell cultures (such as CHO or HEK) can be quickly processed resulting in the capture of cells, cell debris and other biological aggregates in the filter media. The filtrate collected by the 24-well collection plate contains proteins and other sub 0.2 μm particles. This innovative workflow is possible by using multi-layer filtration media and membranes integrated into one device. The top layer features Pall’s Seitz® depth media and efficiently captures whole cells and cell debris. The lower Supor® EKV layer provides an efficient sterile filtration layer.
