title: A microvolume molecular filter.
abstract: A microvolume polymer membrane filter based on Amicon hollow fibers in described which permits separation of  low molecular weight compounds from proteins, and can be used for desalting volumes of 100 microliter or less, or to separate cellular protein debris from perfusates during release studies. The filter has the advantage of being reusable and having almost no void volume.
