Stirring Bars & Rods

Stirring bars and rods are essential tools for achieving consistent and efficient mixing in laboratories. These items are primarily used with magnetic stirrers to ensure thorough blending of solutions in various scientific applications. Stirring bars, including Teflon stir bars, offer chemical resistance and durability, making them usable for a plethora of solutions.

One standout feature is the availability of micro stir bars and small stir bars, ideal for working with limited sample volumes. Spin bars, designed to create a vortex in liquid, come in various shapes and sizes to accommodate different containers and viscosities.

The practical benefits of these features include improved mixing efficiency and reduced contamination risk, as stirring is done without direct contact with the samples. Magnetic stir bar retrievers simplify the retrieval process, preventing damage to both the stir bar and the container.

Available options include a variety of lengths and diameters, catering to specific experimental needs. Stirring rods, often made from glass or plastic, are versatile tools for manual mixing and stirring tasks. Whether you need a magnetic stir bar retriever or specialized micro stir bars, we offer a comprehensive range of solutions for all your stirring requirements.

Thomas Scientific also offers a number of stirrers and vortexers for a variety of lab needs.
