Frequently Asked Questions

Q: What types of pipettes is this rubber suction bulb compatible with?

A: This rubber suction bulb pipette filler is designed to work with standard laboratory pipettes used in chemical, food, agricultural, industrial, and mineral lab settings. Its universal 3-valve design accommodates most common pipette sizes.

Q: How does the 3-valve system work on this pipette filler?

A: The three valves use elastic rubber force to control the flow of liquid. One valve releases air from the bulb, a second draws liquid up into the pipette, and the third dispenses the liquid — giving you precise, hands-on control throughout the pipetting process.

Q: How should I store this rubber suction bulb to maximise its lifespan?

A: Store the suction bulb in a dry, well-ventilated location at 0–35 °C with relative humidity below 80%. Keep it away from acids, alkalis, oils, organic solvents, and heat sources (at least 1.5 metres away). When stored correctly, the product has a shelf life of up to 5 years.
