Abstract: A blowout springless manual air displacement pipette including a mechanical assist for generating a mechanical force opposing a return spring force on a plunger unit to aid a pipette user in locating and maintaining the plunger unit at a “home” position within a pipette body and ready for immersion of a pipette tip in a liquid to be drawn into the tip.
Abstract: An ergonomic, manually precisely controllable return springless air displacement pipette relying on the friction of a piston seal to maintain a plunger unit of the pipette in any axial location established by a user of the pipette.
