  • Patent number: 5568881
    Abstract: The invention is an apparatus for organizing and dispensing pipette tips. A hopper receives bulk pipette tips which pass through a diamond shaped apertures in a sieve and drop into the troughs of a separator which moves the aligned and oriented tips to an organizer which separates the tips and aligns them with storage tubes and drops the tips into tubes where they are stacked and stored. An ejection membrane at the opposite end of the tube allows the tips to be removed into a tip holder box one layer at a time.
