A 24x57mm magnetic stirring bar is a standard laboratory tool with a permanent magnet core sealed in a chemically inert coating. The 24x57mm dimensions typically denote a giant, octagonal bar designed for effective mixing in large-volume or viscous solutions.
Specifications
- Size: 24mm diameter x 57mm length.
- Core material: Alnico V.
- Coating material: PTFE is standard due to its excellent chemical and thermal resistance.
- Chemical resistance: The PTFE coating makes the bar resistant to acids, bases, and many organic solvents, preventing contamination of the solution.
- Temperature range: PTFE-coated bars are highly thermostable and can operate in a wide temperature range, typically from approximately -196 °C to 260 °C (or higher, depending on grade).
- Biocompatibility: The FDA-grade PTFE is non-toxic and often meets FDA and USP
- Class IV requirements, making it suitable for pharmaceutical and biomedical applications.
