The direct connection with samples ends in the aspiration drive remaining constant. favourable displacement pipettes are advised for: Viscous and dense liquids Samples are aspirated and dispensed much more slowly than h2o in a standard air cushion pipette, which may result in inaccurate volumes and residue connected for the tip wall.
