MAGNETIC STIR BAR, 25 MM This magnetic stir bar, with a length (or diameter) of approximately 25 mm, is a versatile laboratory tool designed to facilitate the mixing of liquids using a magnetic stirrer. It features a chemically non-reactive PTFE (Teflon®) coating, ensuring compatibility with a wide range of solutions and ease of cleaning.

Main Benefits

The octagonal or cylindrical shape with a central ring enhances the formation of a strong vortex and reduces friction during stirring. The PTFE coating is chemically non-reactive and resistant to corrosive substances, ensuring durability and compatibility. The strong magnetic core (such as Alnico V or equivalent) maintains connection with the stirrer magnet, reducing rotational slippage even at high speeds. The design is resistant to steam sterilization or high temperatures, allowing use in thermal stirring applications (depending on the specific model).

Composition

Core: High-strength permanent magnet (such as Alnico V or equivalent) Coating: PTFE (Teflon®), providing chemical non-reactivity and smooth rotation

Usage Instructions

Place the magnetic stir bar inside the container holding the liquid to be mixed and position the container on the appropriate magnetic stirrer. The bar will move in response to the magnetic field generated by the device. Use under appropriate laboratory supervision; stirring speed and conditions should be selected based on the type of container, liquid properties, and experimental requirements.

Package Size

Available individually or in multi-packs (such as packs of 5 or 10 pieces), depending on the supplier and model.

Note

The exact shape (octagonal, cross-shaped, cylindrical, oval) and features like heat resistance or steam sterilization capability may vary by manufacturer. Please refer to the product description for precise specifications.
