Ensuring controlled and safe aspiration of liquids is a fundamental safety requirement when using manual volumetric and graduated glassware. Professional laboratory pipette balls and bulbs provide the necessary vacuum and pressure control to handle reagents without manual contact. As a critical safety component of our liquid handling ecosystem, these tools support the manual transfer tasks found in our pipettes range, protecting both the user and the sample.

Frequently Asked Questions
1. What is the difference between the "Normal" and "Flip" LLG Safety Pipetting Ball?
The Normal type uses standard valve control for aspiration and dispensing, while the Flip type features a simplified valve design that allows for easier one-handed operation and cleaning.
2. When should I use silicone (VMQ) teats instead of natural rubber?
Silicone teats are preferred when working with certain aggressive chemicals or when the teats need to be frequently sterilized, as silicone offers better resistance to heat and ozone than natural rubber.
3. Do these bulbs fit all sizes of glass pipettes?
Most safety pipetting balls, especially "Universal" models, are designed with a flexible conical adapter that fits a wide range of pipette neck diameters from 1 mL up to 100 mL.
4. How do I maintain my natural rubber pipette bulbs?
To extend the life of natural rubber, bulbs should be stored away from direct sunlight and heat, and any liquid that accidentally enters the bulb should be rinsed out immediately to prevent chemical degradation.
