Magnetic Stirrer Bar
Product Code : LSK-CL-10069
Magnetic Stirrer Bar (SKU LSK-CL-10069), often called a stir bar or flea, is a PTFE-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. It can serve chemistry, biology and college labs for dissolving, mixing and stirred titrations. Science Lab Supplies, a chemistry lab instruments supplier, quotes the bar from Ambala, India, for schools, colleges, training institutes, tender contractors and distributors.
Specifications
The stirrer bar's construction and use are summed up in the rows below. In short, it is a magnet bar with a PTFE coating, which is chemically resistant and non-stick, so the magnet stays sealed from the liquid and the bar wipes clean; it is made for use with a magnetic stirrer, and the quotation confirms the bar size.

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, with acid delivered from a Burette for Acids.
- Biology labs: mixing buffers and culture media.
Retrieve the bar with a magnetic retriever or stainless steel Forceps rather than fingers, rinse it from a Plastic Washing Bottle (Pisetta) 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 PTFE-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 along with the matching stirrer if required.
Packing, MOQ and Lead Time
You can request a quotation for one stirrer bar or for any larger 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. State the number of bars and your vessel sizes on the contact page, or add the bars to a mixed order in the enquiry cart; the lab tender page explains tender supply.
Frequently Asked Questions
Why is the bar coated with PTFE?
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?
Orders for stirrer bars, from a single piece to a large quantity, are handled by Science Lab Supplies in Ambala, India, for schools, colleges and contractors.
What length is the bar?
Tell us the vessel size you use on the contact page, and the quotation will confirm the length of the bar offered to suit your beakers and flasks.
