Vivaclear centrifugal filters are disposable microfiltration units for the fast and reliable clarification/filtration of biological samples in the range from 100 µl to 500 µl. Vivaclear units feature a high-flux PES membrane of 0.8 µm pore size and can be used in fixed angle rotors accepting 2.2 ml centrifuge tubes. Standard applications are sample clarification before loading onto Vivapure protein purification spin columns, particle removal, plasma or serum filtration, and removal of cells or cell debris from cell lysates or cell supernatants.
