How Does It Compare with Other JLab Stirring Bars?
| Model | Magnet | Distinguishing detail |
|---|---|---|
| This round bar (EL-LS-5053) | Alnico V | Round, with a pivot ring |
| Triangular Magnetic Stirring Bar | Alnico V | Shaped for dissolving solids and stirring up sediments |
| Dumb Bell Magnetic Stirring Bar | Alnico V | For high-viscosity mixtures and round-bottom containers |
| Trapezoidal Magnetic Stirring Bar | Rare earth | Higher torque and efficiency than a conventional bar |
All four are PTFE covered. Pick the round bar for its pivot ring; the other shapes target sediments, thick or round-bottomed work, or extra torque.
What Is the Round Magnetic Stirring Bar Used For?
A stirring bar sits in the liquid while the vessel stands on a magnetic stirrer, whose rotating magnet turns the bar and mixes the contents with no stirrer shaft entering the vessel, so a flask can stay stoppered or covered. Labs use it to prepare solutions, dissolve salts and keep suspensions moving. The PTFE covering resists almost all laboratory chemicals and keeps the magnet out of the liquid. The pivot ring around the middle gives a small contact point, which reduces friction against the vessel floor and helps the bar spin centred.
What to Specify When Ordering
- Shape — round with pivot ring, or another bar shape from the table above.
- Quantity — the number of bars, plus a few spares.
- Magnetic stirrer — a separate item that can be quoted on the same enquiry.
Frequently Asked Questions
What is this stirring bar made of?
It has a PTFE covering over an Alnico V magnet. Alnico is a permanent-magnet alloy based on aluminium, nickel and cobalt.
What does the pivot ring do?
It raises the bar on a narrow ring at its centre, which reduces the contact area with the vessel floor and helps the bar rotate smoothly about its middle.
What details does an export quotation need?
The quantity, the destination country and port or city, delivery terms such as FOB or CIF, packing or labelling requirements, and any tender reference.
