• Magnetic stirrer bars (also known as ‘beads’ and ‘flea’) are tools that rotate and generate stirring action when immersed in a liquid which is placed on a magnetic stirrer plate. 
• These strong magnet bars are coated with polytetrafluoroethylene (PTFE).

Uses:

1. Laboratory Mixing: Used for efficient stirring of liquid samples in laboratory vessels.
2. Homogeneous Mixing: Facilitates homogeneous mixing of substances in a container using magnetic stirring.
3. Chemical Reactions: Applied in chemical laboratories for stirring reagents during experiments and reactions.
4. Sample Homogenization: Utilized to homogenize samples, ensuring uniformity in analytical and research procedures.
5. Biotechnology: Employed in biotechnology processes for mixing components in various applications.
6. Microplate Assays: Used in microplate assays and other high-throughput applications for sample mixing.
7. Viscous Samples: Suitable for stirring viscous liquids or samples that may be challenging for conventional stirring bars.
8. Low Maintenance: Provides a low-maintenance and reusable solution for stirring applications.
9. Reduced Contamination: Minimizes the risk of contamination, especially in sterile or controlled environments.
10. Versatility: Can be used in various vessels, containers, and applications compatible with magnetic stirring.
