The OM11 is a benchtop orbital mixer within a temperature-controlled cabinet. Fan assisted heating coupled with a custom microprocessor regulator ensures accurate temperature control within the cabinet. Separate marked controls and displays for temperature, speed, and timer ensure the OM11 is easy to operate and monitor. What’s more, the OM11’s cabinet cover is hinged at the top to allow easy access to the platform to ensure ease of cleaning.
