Magnetic Stirrer Bar
Product Code : LSK-CL-10069
Magnetic Stirrer Bar (SKU LSK-CL-10069), often called a stir bar or flea, is a Teflon-coated magnet that sits in a beaker or flask and spins when placed on a magnetic stirrer, mixing the solution without a paddle or rod. Chemistry, biology and college labs use it for dissolving, mixing and stirred titrations. Science Lab Supplies, a chemistry lab instruments supplier, provides it from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The bar is a magnet coated in Teflon (PTFE). The coating is chemically resistant and non-stick, so the magnet does not contact or contaminate the liquid and the bar wipes clean. It is intended for use with a magnetic stirrer; the listing does not give a length, which the quotation confirms.

Applications and Experiments for the Magnetic Stirrer Bar
The magnetic stirrer bar is the moving part of any magnetic stirring set-up. Dropped into a beaker or conical flask on a magnetic or heating stirrer, it keeps solutions uniform during dissolving, reactions and titrations, and supports practical work in Class 11–12 chemistry, B.Sc. labs and biology preparation rooms.
- Class 11–12 chemistry: preparing standard solutions evenly.
- B.Sc. practicals: continuous stirring in pH-metric and conductometric titrations.
- Biology labs: mixing buffers and culture media.
Retrieve the bar with a magnetic retriever or forceps rather than fingers, rinse it after each use, and store it away from other magnets and electronic equipment.
Standard Scope of Supply
The Magnetic Stirrer Bar is supplied as a single Teflon-coated bar as described above. The magnetic stirrer that drives it is a separate item, and the quotation will list any quantity of bars you ask for.
Packing, MOQ and Lead Time
Stirrer bars are usually ordered several at a time, and you can request a quotation for any number. It will show packing, delivery time and price, and a heating stirrer, beakers or conical flasks from a laboratory glassware supplier in India can be quoted together.
Science Lab Supplies is a registered exporter with an Importer-Exporter Code and is able to ship to buyers in Qatar, Sri Lanka, Vietnam, Malaysia, Peru and Egypt. Send an enquiry from the contact page, use the enquiry cart for a mixed order, or visit the lab tender page for tenders.
Frequently Asked Questions
Why is the bar coated with Teflon?
Teflon (PTFE) resists most chemicals and does not stick, so the magnet inside stays sealed from the solution and the bar is easy to clean between experiments.
Does it work with the Magnetic Heating Stirrer?
Yes. It is made for use with a magnetic stirrer, including our heating stirrer, which does not include a bar of its own.
Who supplies the Magnetic Stirrer Bar?
Science Lab Supplies supplies it from Ambala, India, and quotes stirrer bars singly or in quantity for schools, colleges and contractors.
What length is the bar?
The length is not stated in this listing. Tell us the vessel size you use on the contact page and the quotation will confirm the bar offered.
