Overhead Stirrer

Overhead stirrers, also called overhead mixers, are commonly used in laboratories to mix or homogenize large volumes of samples including samples with high viscosity. Overhead mixers improve repeatability in experiments while offering more hands-off operation, allowing researchers to focus on other tasks in the laboratory. Often used when a magnetic stirrer is not suitable, overhead stirrers allow researchers to consistently homogenize difficult samples such as those that are highly viscous or require dissolving large quantities of solids in a solvent. When comparing lab overhead stirrers, ensure that the unit is constructed of solvent-resistant material to provide a long operational life. Torque and speed range should also be considered as these vary from manufacturer to manufacturer and can directly impact the stirrer's ability to homogenize samples. Overhead stirrers are available with numerous capacities, consider your sample preparation throughput needs when deciding on which capacity is right for your laboratory.
