The Scientific Industries SI-0401 Microplate Genie Mixer is a vortex mixer (shaker) with variable speed of 750 to 2,700rpm for gentle shaking to rapid vortexing of a single microplate, and can be operated in continuous mode or for timed operation from 1 to 60 minutes. This mixer accepts one microplate of almost any type with a standard Society for Biomolecular Screening (SBS) footprint to provide uniform mixing even in 384-well plates. An accessory kit (sold separately) is available to accept a holder for a polymerase chain reaction (PCR) plate. The mixer has a built-in fan that directs air downward and out of the unit to keep heat from transferring to samples. It can be used in cold rooms or incubators for temperature-sensitive applications, and has European Conformity (CE) marking. Vortex shakers are commonly used in laboratories to mix liquids.

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.

Scientific Industries manufactures laboratory equipment such as shakers and mixers, homogenizers, and incubators under the Vortex-Genie and Genie brands. The company, founded in 1954, is headquartered in Bohemia, NY.
