Pipette Filler 3-Way – Precision-Controlled Suction Bulb for Safe Laboratory Pipetting

A Pipette Filler 3-Way is a high-control suction device used with glass or plastic serological/volumetric pipettes to safely aspirate and dispense liquids. Equipped with three valves/buttons—Aspirate, Dispense, and Air Release—it offers superior control and precision during pipetting. This makes it ideal for chemistry, microbiology, biochemistry, analytical labs, environmental testing, and clinical diagnostics.

The 3-way design eliminates mouth pipetting, enhances safety, and ensures smooth, contamination-free liquid handling.
