vortexer

A vortexer, also known as a vortex mixer, is a laboratory device used to agitate small vials of liquid. It works by using a motor to drive an eccentric mechanism, which causes the sample holder to move in a rapid, circular motion. This motion creates a vortex within the liquid, effectively mixing its contents.

Vortexers are commonly used in biological and chemical laboratories for tasks such as resuspending dried powders, mixing solutions, and homogenizing samples. They are particularly useful for small volumes of liquid where manual shaking would be inefficient or lead to splashing.

There are various types of vortexers available. Some are designed for continuous operation, while others have a touch-activated mode, meaning they only operate when a vial is pressed into the holder. The speed at which the vortexer operates can often be adjusted to suit different mixing requirements. Accessories are available to hold multiple tubes or larger containers.

The primary function of a vortexer is to ensure uniform distribution of components within a liquid sample. This is crucial for accurate experimental results, as uneven mixing can lead to inconsistent concentrations and unreliable data. Despite their simple design, vortexers are essential tools in many scientific disciplines.
