Magnet bar
Product Description
A Magnet Bar, often called a stirring bar or magnetic stir bar, is a laboratory tool used to mix liquids efficiently by magnetic stirring. It consists of a small, coated magnetic rod, typically made from rare-earth magnets encased in chemically resistant materials like PTFE (polytetrafluoroethylene). When placed inside a container with liquid, the magnet bar rotates driven by a magnetic stirrer plate underneath the container, providing uniform and controlled mixing without contamination or the need for manual stirring. Magnet Bars are essential for experiments requiring gentle or continuous mixing, including chemical reactions, sample preparations, and biological assays. Their durable coating ensures resistance to chemicals, heat, and abrasion, making them suitable for diverse laboratory environments.
