Benchmark's Overhead Stirrers feature advanced LCD controls for accurate display of both speed and run time.

Unlike the majority of mixers, the Benchmark series include a support stand. This stand comes complete with all mounting hardware for reliably attaching the mixer at the desired height, providing compatibility with a wide range of vessels (up to 24 inches tall).

The standard, 4-arm propeller is also included, and a wide range of optional propellers and paddles are available separately. (see Manuals/Specifications)

Each of these mixing accessories is available in stainless steel, or inert Teflon. All accessories are easily attached to the mixer without the requirement of any tools or hardware

To prevent against potential corrosion when using hazardous or corrosive solutions, a protective cover is included that prevents splashing on the connection mechanism and improves the long-term safety and reliability of the instrument.
