Hamilton Repeating Dispenser 50 ul

Hamilton PB-600 Repeating Dispenser 50 ul is a manual, positive-displacement pipette designed for the rapid, accurate, and repeatable dispensing of multiple identical volumes from a single aspiration. Unlike air-displacement pipettes, which rely on a cushion of air, the PB-600 uses a piston that directly displaces the liquid. The manual trigger allows the user to quickly dispense a preset volume multiple times by simply pushing the lever, significantly speeding up tasks like plate filling or serial dilutions.

Used, in great condition.
