Vortex-Genie 2T, 120V. The Vortex Genie-2 T has a timer function which allows both touch & hands-free mode & automatically turns the unit off after set time. The touch Mode is 1-60 seconds & the hands-free (switch activated Start/Stop) mode is 1-60 minutes or can be set at a continuous untimed. With Genie-2 T there is no need to watch the clock as the unit automatically stops at set time with the accuracy of +/- 5%. The vortexing time is constant, no matter the day or operator. The variable speed control allows slow speed shaking action up to high speed vortexing. In addition, each attachment is designed to produce different mixing actions, allowing users to choose the correct action for each application. A broad range of attachments allows for mixing of almost all common tubes or containers for hands-free or touch operation. A 3-position power switch operates with continuous action or "Touch On" control. Tough metal housing provides a stable platform for all types of mixing.
