Pipette Filler Bulbs are pear-shaped silicone rubber bulbs used for controlled filling and dispensing with compatible glass or plastic pipettes. The flexible bulb helps create a seal on standard pipette stems and gives simple squeeze control for everyday liquid handling. This is a bulb accessory, not a pipette, so it is used together with a separate glass or plastic pipette. It is especially useful where you want a straightforward, easy-to-clean alternative for routine aspiration and delivery.
♡ Why we love it: These bulbs are simple, durable, and easy to work with, which makes them a very practical bench staple. The silicone material gives a reliable grip and smooth squeeze control without adding much maintenance.
