ABSTRACT:
A filter for a pipette tip is provided, comprising a plurality of vertically-oriented cylindrical micro fibers cohesively bundled in adjoining columns which are composed of a core of an autoclavable material and an outer coating of a hydrophobic material. The micro fibers are packed together such that each micro fiber is compressed against the other fibers and the inner surface of the pipette tip. The compression of the fibers creates vertically-oriented pores interstitially between the micro fibers, each pore having a pore size at various points within the filter. Each filter has an equal predetermined density of micro fibers per square millimeter in its uncompressed state, such that when the filter is compressed, its pore sizes will be consistent with another filter used in a pipette tips of the same size and shape.
