Pipette Filler Bulbs - Silicone Rubber - 10ML

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.

Key Properties Material: Silicone rubber Form: Pear-shaped pipette filler bulb Suitable For: Glass or plastic pipettes Feature: Good seal on standard pipette stems Reusable Easy to clean Chemically Resistant Non-Conductive Corrosion Resistant What It's Used For Filling and dispensing liquids with compatible pipettes Pre-wetting pipettes before measurement Routine transfers in teaching labs and sample preparation Everyday liquid handling in workshops and classrooms Controlled aspiration and delivery of small liquid volumes Who It's For This Product Is For: Users working with glass or plastic pipettes Teaching labs and sample preparation DIY formulators handling small liquid quantities Anyone wanting a simple silicone squeeze bulb This Product Is Not For: Use without a compatible pipette Very high-heat exposure Use with damaged or poorly fitting pipette stems Anyone looking for a three-valve rubber filler How To Use As a Pipette Bulb: Attach the bulb firmly to a dry pipette stem.

Squeeze the bulb to expel air, then place the pipette tip into the liquid. Slowly release pressure to aspirate to the required volume, keeping the tip below the liquid surface. Dispense by gently squeezing or easing pressure as needed. Detach and rinse after use. Processing Tip: Pre-wet the pipette when needed to help improve consistency during measurement.

Safety Instructions Clean with mild detergent and water, then rinse and air dry. For quicker turnaround, wipe with isopropyl alcohol and allow to dry fully. Avoid sharp objects and excessive heat. Inspect regularly for cracks or loss of elasticity. Replace if worn or damaged. Keep out of reach of children when not in use.
