Three-Valve Rubber Pipette Filler Bulb (Best Quality)

Use this three-valve rubber pipette filler bulb as a manual accessory for laboratory pipetting. Supplied as one piece, it uses the elastic action of the bulb and its valves to help draw liquid into a compatible pipette.

Prepare your pipetting setup by checking the bulb's fit with your pipette and following the supplier's valve-operation instructions.

Capacity and compatibility

The earlier description mentions 25 mL without clarifying whether this refers to bulb volume or supported pipette capacity. Confirm the intended capacity and pipette fit before ordering; no selectable size options are currently listed.

Measurement accuracy depends on the pipette and technique, not the filler bulb alone. Pipettes are not documented as included.

Use and care

Confirm rubber compatibility with your chemicals and follow the supplier's cleaning instructions. Avoid drawing liquid into the bulb unless the manufacturer's instructions permit it. Inspect the bulb and valves for damage before use.

Chemical-resistance ratings, temperature limits, autoclave suitability and service-life guarantees are not specified. Natural rubber may contain latex; confirm material details where latex sensitivity is a concern.
