These multiposition stirrers are designed for synchronous stirring. They feature magnetic-coil technology that provides noiseless and consistent stirring on all positions. The powerful drive is 100% wear- and maintenance-free, has no moving parts, and is suitable for continuous operation. Adjust speed in 10 rpm increments; stirrer speed remains constant even when load changes. An easy-to-use foil keypad features a digital display, an error code display, and a reverse rotation switch for superior mixing results. The closed, compact design allows easy cleaning and protects the equipment against the penetration of liquids. Stirrers are available in five-, ten-, and fifteen-position configurations.
