Free!
A pipette bulb is a safe, easy pipetting aid for drawing and dispensing liquids with glass or plastic pipettes. Its simple three-valve control gives smooth, precise aspiration and release. Ideal for teaching labs, routine QC, and everyday transfers. Durable, chemical-resistant material, no power required, and compatible with multiple pipette sizes—an affordable, reliable upgrade from mouth pipetting.
Description
A pipette bulb is a simple, dependable pipetting aid used to draw and dispense liquids with glass or plastic pipettes. It replaces unsafe mouth pipetting and gives you smooth, controlled aspiration and delivery. Most bulbs feature a three-valve design—typically marked for air release, suction, and expulsion—so you can set the meniscus precisely without splashing or overfilling. The bulb fits common serological and volumetric pipettes used in labs, classrooms, and testing facilities.
Key features and benefits:
• Safe, hands-off alternative to mouth pipetting; supports good laboratory practice.
• Three-valve control for accurate aspiration and fine release.
• Compatible with a wide range of pipette sizes for everyday flexibility.
• Durable rubber or silicone construction with good chemical resistance.
• Lightweight and portable; no batteries, power, or maintenance required.
• Available in latex-free options for sensitive users.
Typical uses and applications:
• Routine solution transfers in research and quality control labs.
• Teaching laboratories for safe student training.
• Sample preparation in clinical, food, pharmaceutical, and environmental testing.
• General liquid handling where precision and safety are important.
How it compares:
• Versus motorized pipette fillers: bulbs are lower cost, lighter, and ideal for quick tasks; motorized fillers offer faster throughput and integrated filters.
• Versus manual pipette controllers with triggers: bulbs are simpler and easier to clean, while trigger controllers may offer finer speed modulation.
Good to know:
• Pair with properly calibrated pipettes to maintain accuracy.
• Rinse after use, keep away from strong oxidizers, and store dry to extend service life.
• Choose solvent-compatible materials and a latex-free model if needed.
