The Scientific Industries SI-A236 Digital Vortex-Genie 2 Mixer is a vortex mixer (shaker) with variable speed of 500 to 3,000rpm for gentle shaking to rapid vortexing of samples, can be operated by touch or in continuous mode, and features a timer that can be set from 1 to 99 seconds in touch mode and 1 to 99 minutes in continuous mode. It stops automatically at the end of the programmed time. This mixer comes with a removable cup head for a single tube up to 40mm in diameter and 200mm in length, and a 3" platform for a beaker, a flask, or multiple tubes. Additional interchangeable mixing heads for holding vessels such as microtubes and microplates are available (sold separately). The mixer has electronic controls with an LED display that shows speed and time for accurate, repeatable results. Its metal housing and shock-absorbing feet provide a stable platform to help prevent walking. It can be used in cold rooms and incubators, 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.
