Thermo Fisher, 4500020, Finnpipette™ Digital Variable Volume Single Channel Pipettes

The Thermo Scientific Finnpipette Digital is an adjustable-volume, single-channel manual pipette for accurate transfer of microliter-scale aqueous samples. This variant covers 0.5–10 µL and uses an air-displacement mechanism with disposable polypropylene pipette tips. Its integrated volume display makes the selected setting visible on the body, supporting repeatable setup during PCR master-mix preparation, enzyme additions and other small-volume liquid-handling tasks. Use manufacturer-listed compatible Finntips, pre-wet the tip where appropriate and maintain a consistent aspiration angle and plunger technique. At sub-microliter volumes, evaporation, pipetting speed and tip fit can materially affect delivered volume; verify performance gravimetrically under laboratory quality procedures. The pipette is not a positive-displacement model and should not automatically be treated as suitable for highly viscous, volatile or foaming liquids without a validated method.
