TEOS 200 Series RS232 Remote Controlled Orbital Shakers (Mixers)

            The TEOS 200 series are RS232 interfaced remote controllable shakers (mixers) capable of both manual and/or remote control. The small footprint of these units enables simple integration with many automated platforms. Mounting of the unit can be customized to match integration specifications (customized mixing).

            The variable amplitude and speed TEOS orbital shakers/mixers are based on a novel design principle (US Patent 5,988,869).  A plate holding platform floating on air bearings and air driven high speed turbines with calibrated eccentric weights combine to provide unique capabilities in vortex generation, repeatable "Zero X-Y" return position and high general reliability. The latter is essential for robotic interface and integration with other automated platforms.

The TEOS 200 series mixers have a set of air powered turbines (60 - 80 PSI, 1 SCFM) and a separate controller powered by a standard 110 VAC to 220 VAC power supply.


TEOS 200 series mixers are supplied with simple to use control software. Optimal speed and amplitude (e.g. stable vortex generation) can be selected and  "locked" by the controller for the duration of the run.

             Three models are available in the TEOS 200 series. (See description below). The TEOS 200 and 220 are single speed mixers suitable for specific plate formats. The TEOS 250 is a combined dual-speed mixer for all plate formats and represents the best value. All models are provided with the TEOS software CD-ROM w/manual, ActiveX Control and ASCII commands with sample Visual Basic 6 PC interface for communication directly with embedded microprocessor. The Source Code is also included for custom program development. Also packaged with each model are: TEOS Control Box w/controller and power supply, control cable, RS232 serial cable, air supply tubing (6, ID / female quick connect), operating instructions and replacement vacuum filters.


               Various video clips taken with high speed camera and in real time show effective vortex generation in different type micro titer plates. (Vortex in 384 well plate, Vortex in 1536 well plate, Mixing in 384 well plate).
