Which JLab Stirring Bar Fits the Job?
| Bar | Intended for | Magnet |
|---|---|---|
| Dumb bell (EL-LS-5055) | High-viscosity mixtures and round-bottom containers | Alnico V |

For thick mixtures or a flask with a curved floor, the dumb-bell bar is the one to choose; where the liquid is thin and the vessel flat, the round or triangular bars cover most routine work.
What Is the Dumb Bell Stirring Bar Used For?
Viscous liquids resist flow and are hard to keep moving, and a round-bottom flask offers no flat floor for a bar to spin on. The dumb-bell bar — wider at each end and narrower in the middle — is the JLab shape intended for both situations, for example when stirring a thick reaction mixture in a round-bottom flask during synthesis or reflux. The stirrer drives it through the glass, so no shaft passes through the neck and the flask can stay stoppered or connected to other apparatus. The PTFE surface resists almost all laboratory chemicals and keeps the magnet sealed from the mixture.
What to Specify When Ordering
- Shape — dumb bell, or other bar shapes for different vessels.
- Quantity — one bar per flask in use, plus spares.
- Stirrer or hotplate stirrer — separate items that can be added to the enquiry.
Frequently Asked Questions
When should I use a dumb-bell stirring bar?
With high-viscosity mixtures and in round-bottom containers, the two uses this bar is intended for.
What materials is it made from?
A PTFE exterior with an Alnico V magnet inside.
What should I send for an export quotation?
The quantity, destination country and port or city, preferred delivery terms such as FOB or CIF, packing or labelling needs, and any tender number.
Who is the manufacturer?
JLab (Jain Laboratory Instruments Pvt Ltd), which makes the bar at its Ambala works in Haryana, India.
OEM Manufacturer
Behind the JLab name is Jain Laboratory Instruments Pvt Ltd, a scientific lab equipment manufacturer in India incorporated in 2017, with its works on Hargolal Road, Ambala, Haryana. The dumb-bell bar is made there in-house rather than traded, so schools, colleges, dealers and importers buy direct from the maker and can come back to the same works for matching bars later. JLab exports worldwide and ships to buyers in every region — for example Uruguay in South America, Taiwan in East Asia, Lesotho in Southern Africa, Sri Lanka in South Asia and Sudan in North Africa. See the JLab lab tenders page for tender supply.
