Choose this listing when you want a valved rubber bulb described by its 54 mm diameter and supplied in packs of 10. The three-way filler and the bulb filler are listed by capacity instead, and the other Pipette Bulb listing offers a run of named sizes — useful if one lab needs bulbs for several pipette sizes.
What Is the Pipette Bulb Used For?
Mouth pipetting is not safe in a teaching lab, so a pipette bulb is fitted to the top of a glass pipette to draw liquid up and let it out under control. Typical uses are measuring out the solution for an acid–base titration in class 11 and class 12 chemistry practicals, transferring reagents in college analytical labs, and handling stains and buffers in biology work. On a three-valve bulb of this kind, one valve is pressed while squeezing to expel air, a second draws liquid up past the mark, and the third lets it run down to the mark and out into the receiving flask.
Push the pipette only a short way into the bulb’s lower end and keep the liquid below the bulb: liquid drawn into the rubber spoils the valves and can carry over into the next sample. Rinse the stem with distilled water after use, let it dry, and store the bulbs away from heat and direct sunlight so the rubber stays soft.
What to Specify When Ordering
- Quantity — the bulbs are listed in packs of 10 and the minimum order is 10 units; many schools allow one bulb per pipette in use plus spares.
- The pipettes you use — give the pipette type and capacities so the fit can be confirmed, as the listing does not state them.
- Material — say if you need a particular bulb material, since the listing heading also mentions PVC.
- Pipettes and fillers — add pipettes or another filler type from the list below to the same enquiry.
Frequently Asked Questions
What is a pipette bulb used for?
It fills and empties a pipette by finger pressure so that no one has to suck liquid up by mouth. That makes routine pipetting in school and college practicals safer, especially with acids, alkalis and stains.
How large is this bulb?
The bulb is 54 mm in diameter and made of soft rubber. The listing does not give the pipette sizes it fits, so mention your pipettes when you enquire and JLab will confirm.
What do the three valves do?
They control the flow of liquid into and out of the pipette. In practice one valve lets you squeeze the air out, one draws liquid up and one releases it, so the bulb stays on the pipette while you set the level and deliver the liquid.
How is it different from the three-way pipette filler?
Both are valved fillers worked by finger pressure. The three-way filler is listed as a red 50 ml unit, while this bulb is described by its 54 mm diameter and sold in packs of 10; ask JLab if your choice depends on another feature.
Are pipettes included?
No. This listing covers the bulbs only; glass pipettes are separate items, linked below, and can go on the same enquiry.
What should an export enquiry include?
The number of bulbs, the pipettes they must fit, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling instructions, and a tender reference if there is one.
Who manufactures this pipette bulb?
JLab — Jain Laboratory Instruments Pvt Ltd — makes it at its works in Ambala, Haryana, India, and quotes for it directly.
