H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Vortex shakers mix small amounts of liquid in laboratory containers for biochemical, microbiological, and other applications. A vortex shaker can be analog or digital and is commonly an automated, electrically powered, benchtop unit with a base that holds a rubber cup or a platform that spins off center. The user places a test tube, beaker, or other small vessel of liquid onto the spinning cup or platform, creating a vortex to mix the liquid. Some models can hold multiple containers, often by an accessory attached to the base. Additional features may include fixed or variable speeds, touch or hands-free operation, and various voltages.
