Benchmark's Overhead Stirrers feature advanced LCD controls for accurate display of both speed and run time. The stirrers include a support stand complete with mounting hardware. The mixer is easily attached at the desired height for compatibility with a wide range of vessels (up to 24 inches tall). The stand and 4-arm propeller are included. A wide range of optional propellers and paddles are available separately. Each of these mixing accessories is available in stainless steel or inert Teflon. All accessories are easily attached to the mixer without tools or hardware. To guard against potential corrosion when using hazardous or corrosive solutions, a cover fits over the connection mechanism to protect the unit and improve the long-term safety and reliability of the instrument.
