Syringe/ Piston strategies wipe the suggestion walls clean up. Liquid examples: Tween™ twenty, sulfuric acid, concentrated DNA / RNA, glycerol risky liquids Evaporation may result in inaccuracy as well as pipette dripping in standard air-cushion pipettes, positive more info displacement pipettes stop vapors from shifting into air Place.
